Good Quality 97% Potassium Cyanate for Weed Killer Heat Treatment CAS 590-28-3

97% Potassium Cyanate with CAS No.590-28-3 is a high-purity inorganic crystalline chemical refined through strict synthesis, filtration and drying procedures, widely supplied for agricultural weeding, metal heat treatment and organic chemical synthesis industries. The product appears as pure white fine crystal powder, free of visible impurities, caking and foreign particles. Our factory controls the effective content above 97%, with low chloride, carbonate and heavy metal impurities, fully meeting international industrial and agricultural raw material standards for export.

In agricultural fields, potassium cyanate serves as an efficient contact herbicide. When dissolved and sprayed on weed foliage, it can rapidly penetrate plant cell tissues, disrupt the normal metabolic system of weeds, and lead to withering and death of various annual broadleaf weeds and miscellaneous grasses. It is suitable for orchard, wasteland and non-cultivated land weeding management, with fast action speed and no long-term residual pollution to soil in standard dosage. Besides weeding, it also acts as a soil disinfection agent to inhibit the reproduction of harmful fungi and nematodes in topsoil.

For metal heat treatment industry, it is a core raw material for low-temperature cyaniding and carbonitriding processing. During surface thermal treatment of steel parts, potassium cyanate decomposes to release active carbon and nitrogen elements, forming a uniform hardening layer on the workpiece surface. This treatment greatly improves surface hardness, wear resistance and corrosion resistance of hardware accessories, gears, bearings, fasteners and auto mechanical components. Compared with complex cyanide heat treatment agents, this product has milder reaction conditions, easier waste liquid treatment and lower comprehensive production cost for metal processing factories.

In fine chemical synthesis, it is an indispensable intermediate for manufacturing urea derivatives, biocides, pharmaceutical raw materials and dye additives. It participates in addition and cyclization reactions to produce multiple high-value organic chemicals, favored by pharmaceutical and dye processing manufacturers.

Our production line adopts fully enclosed automated equipment to avoid external contamination. Every batch undergoes complete laboratory inspection, including main content, water insoluble matter, moisture, pH value and heavy metal limit. We can provide full set of export documents: COA certificate, MSDS safety data sheet, customs inspection report and transportation guidance. The product is hygroscopic, so we adopt moisture-proof sealed packaging: 25kg fiber drum with PE inner bag for bulk shipment, and 100g / 500g vacuum aluminum foil bags for customer sample testing. It must be stored in cool, dry, ventilated warehouse, sealed away from moisture, acid substances and high temperature environment, with 24 months shelf life under intact original package.
