Product Overview

If you are evaluating nonanoic acid, you are likely facing one of these three key challenges:

Nonanoic Acid, or nonanoic fatty acid, is an organic straight-chain saturated acid that has the chemical formula CH3 (CH2)7COOH. It occupies a unique place in the specialty chemical market as a C9 structural element due to its excellent balance of hydrophobicity and hydrophilicity.

Physical and Chemical properties

At room temperature, nonanoic is an oily, transparent liquid with a rancid smell. Its molecular mass is 158.24g/mol. Its boiling point is 254degC and its melting temperature is 12degC. Nonanoic Acid is poorly soluble in water but readily soluble with organic solvents like ethanol, chloroform, ether and acetone. Nonanoic Acid’s carboxyl group allows it to be converted into salts, esters and amides.

Production and Industrial Status

Currently, nonanoic acids are produced commercially by ozone decomposition, a process that is environmentally friendly and also yields azelaic as a side product. The bio-based production method of nonanoic acids using natural oils attracted significant attention in recent years. This is aligned with the global trend toward green development within the chemical industry. Look Chemical provides high-purity, nonanoic acids to meet growing demand in industries like agriculture, plastics and personal care.

Safety & Handling

Hazard Information

GHS Classification

  • Corrosive fluid categorized as dangerous products (UN3265, Class 8) requires thorough treatment throughout handling and storage space. Below are essential safety measures to take into consideration to make certain safety and security.

Handling

During handling, it is crucial to use personal safety devices (PPE) that is resistant to destructive substances, such as handwear covers, goggles, or aprons, to prevent straight contact with skin and eyes. Prior to starting operations, constantly check the product packaging to guarantee it is intact and devoid of leakages or damages. When transferring the material, use high-density polyethylene (HDPE) or stainless-steel pumps and tubes for improved deterioration resistance and safety. To avoid unintended spills or leakages, avoid influence, going down, or misuse. Additionally, regulate the circulation rate during transfer to minimize spilling. In case of an unexpected spill, quit working quickly and follow the emergency treatments detailed in the Product Safety Data Sheet (MSDS). Make sure that the procedure location is well-ventilated to prevent vapor buildup.

FAQ-Technical Q&A

A: Nonanoic acid is a contact herbicide with no systemic translocation. It acts within hours by disrupting cellular membranes, leading to rapid desiccation of treated plant tissue. It leaves no soil residual and does not affect plant roots.

This mode of action makes nonanoic acid particularly suitable for organic agriculture programs, resistance management strategies, and rapid burndown applications. However, because it does not translocate, repeat applications may be required for the control of perennial weeds. Its strategic value lies in rotation programs designed to interrupt herbicide resistance cycles.

A: Nonanoic acid should be stored in a cool, dry environment using corrosion-resistant containers such as stainless steel or properly lined drums. Contact with strong oxidizing agents and strong bases should be avoided.

In formulations, its antimicrobial and herbicidal efficacy is pH-dependent. Activity is highest at pH values below its pKa (approximately 4.96), where the protonated form predominates and more readily penetrates biological membranes. Formulators typically adjust or buffer systems accordingly to maintain optimal performance.

A: Yes. We offer specific grades manufactured under stringent quality control systems to meet USP, EP, or FDA 21 CFR requirements for indirect food-contact applications. Upon request, we provide full certification and supporting regulatory documentation to facilitate customer registration and compliance processes.

A: Nonanoic acid is well recognized for its rapid environmental degradation, which represents a significant advantage when developing products aligned with sustainability and regulatory acceptance requirements.

A: Synergistic use is where nonanoic acid demonstrates its greatest value. In agrochemical formulations, it is frequently combined with other herbicides (such as glufosinate) or adjuvant oils to improve penetration, rainfastness, and overall efficacy.

In preservative systems, nonanoic acid is commonly blended with other medium-chain fatty acids (e.g., caprylic and capric acids) to achieve broader-spectrum antimicrobial coverage. We provide technical guidance on effective synergistic ratios based on the intended application.

A: Each production batch is verified using gas chromatography (GC) with flame ionization detection (FID). Certificates of Analysis report not only overall purity but also the detailed profile of related fatty acids (e.g., C8 and C10 homologs), moisture content determined by Karl Fischer titration, and product appearance.

This analytical approach ensures consistent, predictable performance in downstream formulations and chemical reactions.

A: Nonanoic acid functions as a mild, film-forming anodic corrosion inhibitor. While it is generally less aggressive than certain synthetic inhibitors, its key advantages include high biodegradability and lower ecotoxicity.

These properties make it well suited for environmentally sensitive applications, such as closed-loop heating systems, cooling circuits, and marine or near-marine environments where discharge considerations are critical.

A: Yes. In addition to pure nonanoic acid, we supply various derivatives, including metal salts (such as zinc or sodium nonanoate) and customized pre-blended mixtures with other medium-chain fatty acids. These tailored solutions are designed to simplify customer manufacturing processes and optimize end-use performance.

Concerning storage space problems, this material needs to be kept in an amazing, dry, and well-ventilated storehouse, purely away from direct sunlight, with ambient temperature levels not surpassing 35 ° C. Containers have to stay closed in their initial problem and must not be opened unnecessarily. Pallets or shelves need to not relax straight on the ground; instead, corrosion-resistant shelving is advised to enhance safety.

Seclusion is another important facet of storage space. Corrosive fluids need to be maintained different from oxidizers, strong bases, and other inappropriate materials such as foods. In addition, preserve a risk-free distance from other groups of harmful chemicals to minimize the danger of cross-reactions.

For stock administration, it is a good idea to comply with a First-In-First-Out (FIFO) system to make sure that older stock is utilized initially, lessening threats associated with expired chemicals. On a regular basis check packaging for any indications of swelling or leak, and if irregularities are detected, immediately resolve them based on the Safety and security Data Sheet (SDS) directions.

The storage location need to be outfitted with required emergency situation reaction products and centers, such as fire extinguishers and products for soaking up spills (e.g., sand or vermiculite). Make certain that safety and security warning signs and in-depth operational instructions are clearly shown in the storehouse to make sure that team can promptly respond to possible occurrences.

By adhering strictly to these standards, threats can be properly minimized while securing both workers and the setting.
