Basic Introduction to Cuprous Cyanide
Cuprous Cyanide (Chemical Formula: CuCN, CAS No. 544-92-3, IUPAC Name: Copper(I) cyanide) is an off-white to light cream-colored insoluble powder featuring high thermal stability and unique chemical reactivity. As an inorganic copper(I) compound, it serves as a fundamental copper donor and cyanating precursor across high-tech electronics, specialized electroplating systems, and complex organic syntheses.
As precision manufacturing standards advance globally, Shandong Look Chemical Co., Ltd. supplies stabilized, high-assay Cuprous Cyanide tailored for demanding processing lines. In the field of electronic chemicals, where particulate purity and metal consistency dictate production yields, our refined Cuprous Cyanide offers exceptional batch uniformity, low insolubles, and controlled metal impurity levels. It functions as a vital raw material in electronic-grade copper plating baths, semiconductor packaging metallization, and specialized organocuprate reagent formulations.

Cuprous Cyanide Application
Cuprous Cyanide’s chemical stability and copper-donating efficiency enable wide application across high-tech electronics and specialized synthesis:
A. Electronic Chemicals & Microelectronics Metallization
In modern electronic chemicals formulations, Cuprous Cyanide provides precise copper ions and cyanide ligands required for high-reliability plating:
Selective Copper Electroplating: Acts as a key ingredient in cyanic copper plating chemistries used for printed circuit boards (PCBs), lead frames, and electronic component contacts, delivering excellent throwing power and smooth deposit morphology.
Diffusion Barrier Metallization: Used in preparing specialized plating solutions that create dense, corrosion-resistant copper barrier layers in microelectronic packaging.
B. Organic Synthesis & Organocuprate Reagents
Rosenmund-von Braun Reaction: Serves as a reliable cyanating agent for converting aryl halides into aryl nitriles at elevated temperatures.
Organocuprate Generation: Reacts with organolithium or Grignard reagents to form Gilman reagents (R2CuLi), essential for selective conjugate additions and cross-coupling reactions in fine chemical manufacturing.
C. Surface Treatment & Specialty Coatings
Anti-Fouling Formulations: Serves as an active biocide component in specialized marine anti-fouling coatings.
Alloy Plating Baths: Acts as a copper source in cyanide-based brass and bronze alloy plating solutions.
Certifications & Regulatory Compliance
Due to the hazardous nature and specialized handling required for inorganic cyanides, Shandong Look Chemical operates under strictly audited international safety, quality, and environmental protocols:
ISO 9001:2015 Quality Management System: Standardized processing controls ensuring exact copper content, batch uniformity, and low trace contaminants.
ISO 14001:2015 Environmental Management System: Eco-conscious chemical processing equipped with closed-loop neutralization and waste treatment systems.
GHS & SDS Compliance: Safety Data Sheets (16 sections) compiled strictly according to the UN GHS guidelines, available in multi-language formats for global shipping safety.
REACH Compliance Support: Complete technical documentation and dossier support to enable regulatory-compliant imports into European Union markets.
Class 6.1 Toxic Substances DG Transport Accreditation: Certified UN-rated steel drums with hermetically sealed inner liners, compliant with IMDG and IATA regulations for secure hazardous materials transportation.
At SD Look Chemical, every production lot of Cuprous Cyanide undergoes rigorous laboratory verification before dispatch. Our quality control center uses standardized analytical methodologies to confirm product integrity against strict industrial criteria.
Typical Certificate of Analysis (COA) Specifications:
Appearance: Off-white to cream powder (Conforms / Visual Inspection)
Purity / Assay (CuCN): ≥ 99.0 % (Typical Result: 99.4 % / Complexometric Titration)
Copper (Cu) Content: ≥ 70.5 % (Typical Result: 70.8 % / Iodometric / EDTA Titration)
Acid-Insoluble Matter: ≤ 0.05 % (Typical Result: 0.02 % / Gravimetric Method)
Free Cyanide (NaCN eq.): ≤ 0.10 % (Typical Result: 0.04 % / Titrimetric Method)
Iron (Fe): ≤ 20 ppm (Typical Result: 8 ppm / ICP-OES)
Moisture / Loss on Drying: ≤ 0.50 % (Typical Result: 0.22 % / Thermal Drying at 105°C)
EDTA / Iodometric Titration: Accurately measures total active copper content (≥70.5%) to guarantee predictable chemical stoichiometry in downstream bath chemistries.
Gravimetric Filtration Testing: Crucial for applications in electronic chemicals, controlling acid-insoluble residue prevents bath filtration clogging and particle defects on plated substrates.
ICP-OES Heavy Metal Screening: Quantifies trace iron, lead, and nickel impurities to ensure strict compliance for electronic-grade copper processing.
Controlled Sample Storage: Retained samples from each batch are kept in air-tight, climate-monitored storage for 24 months to support post-delivery trace verification.
FAQ
A: We offer Industrial Synthesis Grade (Assay ≥98.5%) and High-Purity Electroplating Grade (Assay ≥99.0%, Cu ≥70.5%). For specialized needs within electronic chemicals, we provide custom-tailored controls on acid-insoluble matter and trace heavy metals upon technical request.
A: Cuprous Cyanide is classified as a Class 6.1 toxic substance. It must be stored in cool, dry, well-ventilated dedicated hazardous storage rooms, strictly segregated from acids, oxidizers, and food items. Containers must remain tightly sealed under nitrogen or in moisture-resistant UN-approved drums to prevent hydrogen cyanide gas liberation upon acid contact.
A: Yes. We provide sample quantities (100g to 1kg) for qualified industrial clients to conduct laboratory evaluation. Every sample or commercial shipment is accompanied by a batch COA, SDS, and technical guidance.
A: As an experienced chemical exporter, Shandong Look Chemical coordinates all hazardous goods declarations, UN packaging certifications, and customs clearances. We supply goods in UN-approved steel/fiber drums with double PE inner liners, ensuring safe and compliant transport by sea or air.
