Product Introduction:
Sodium Dimethyldithiocarbamate (CAS No. 128-04-1, commonly referred to as SDMC or SDDC) is an organosulfur compound belonging to the dialkyl dithiocarbamate family. It is commercially offered as a pale yellow to clear aqueous solution (~40% concentration) or an off-white to yellowish crystalline powder (Assay ≥95.0%). Owing to its strong polar dithiocarbamate functional group (-NC(=S)S-), it displays notable coordination affinity toward transition metals.
Driven by modern industrial purity requirements, Shandong Look Chemical Co., Ltd. produces stabilized, high-performance Sodium Dimethyldithiocarbamate tailored for specialized technical fields. Within the electronic chemicals sector, where sub-ppm trace metal removal and liquid formulation stability are essential, SDMC functions as a high-efficiency heavy metal scavenger, chelating agent in microelectronic post-etch cleaning solutions, and specialized process agent in printed circuit board (PCB) manufacturing.

Sodium Dimethyldithiocarbamate Uses:
The dual-action sulfur-donor structure of Sodium Dimethyldithiocarbamate permits high-affinity metal binding and biological control across key technical industries:
A. Electronic Chemicals & Semiconductor Wastewater Treatment
In modern electronic chemicals manufacturing and microelectronic processing, Sodium Dimethyldithiocarbamate plays a vital role in contamination control:
Selective Heavy Metal Precipitation: Acts as a chelating scavenger in microelectronic rinse waters, rapidly precipitating copper (Cu2+), nickel (Ni2+), lead (Pb2+), and zinc (Zn2+) into dense, insoluble chelate complexes even at low concentrations.
Post-Etch & Micro-Erosion Formulations: Utilized as a specialized additive in semiconductor substrate cleaning solutions to capture free metal ions and prevent cross-contamination during wafer processing.
B. Industrial Water Treatment & Biocidal Control
Circulating Cooling Water Biocide: Functions as a broad-spectrum industrial biocide and algicide, preventing slime-forming bacteria and fungal growth in paper pulp systems, sugar mills, and industrial cooling towers.
Cutting Oil & Lubricant Preservation: Serves as a biostatic additive in water-miscible metalworking fluids, extending fluid service life by preventing microbial degradation.
C. Polymerization & Mining Flotation
Rubber Vulcanization & Short-Stopper: Used as a radical polymerization terminator (short-stopper) in styrene-butadiene rubber (SBR) synthesis and as a secondary vulcanization accelerator in natural and synthetic latex.
Mineral Ore Flotation: Acts as a selective collector for copper, lead, and sulfide minerals in mining separation processes.
Related Industry Q&A
Q1: What grade options are available for Sodium Dimethyldithiocarbamate, particularly for electronic chemical applications?
A: We supply both 95% high-purity solid powder and ~40% standardized aqueous solution. For customers in electronic chemicals and high-precision water treatment, we offer customized control over free alkali content, color index, and background trace metal limits based on technical specifications.
Q2: How should Sodium Dimethyldithiocarbamate be stored to maintain long-term chemical stability?
A: SDMC powder is hygroscopic, while the aqueous solution is sensitive to low temperatures and acidic conditions. Containers should be stored tightly sealed in a cool, dry, and well-ventilated area away from direct sunlight, acids, and strong oxidizers. Acidic environments must be avoided as they can cause decomposition and toxic carbon disulfide gas release.
Q3: Can Shandong Look Chemical provide evaluation samples and custom packaging solutions?
A: Yes. We provide sample quantities (100g to 1kg) for laboratory validation and process testing upon request. Industrial packaging options include 25kg moisture-proof woven bags with inner PE liners, 200kg HDPE drums, and 1000kg IBC totes. Custom trial quantities starting from 1kg can also be arranged.
Q4: How does Shandong Look Chemical handle export logistics and dangerous goods documentation for SDMC?
A: As a certified chemical manufacturer and exporter, we provide comprehensive documentation for international shipments, including UN packaging certificates, GHS-compliant Safety Data Sheets (SDS), and Certificate of Analysis (COA) for every dispatched lot, ensuring full compliance during ocean or land transportation.
