FAQ - Technical & Supply Chain
-
Q:
Does CAS 540-72-7 cover both solid Sodium Thiocyanate and commercial aqueous solution?
A: CAS 540-72-7 identifies sodium thiocyanate, NaSCN, but the quotation must still distinguish dry crystals or powder from an aqueous solution and state the solution concentration. Do not substitute ammonium, potassium or calcium thiocyanate. Specify the required form and concentration. -
Q:
What is Sodium Thiocyanate used for?
A: It is used in acrylic-fiber spinning and solvent systems, metal treatment, photochemical and electroplating processes, and as a chemical intermediate or analytical reagent. The required purity and cyanide-related impurity profile depend on the process and whether it is supplied as solid or solution. -
Q:
Which batch limits should be compared for Sodium Thiocyanate?
A: For solid material, compare NaSCN assay on the agreed basis, water or loss on drying, pH, color, iron, sulfate, sulfide, chloride and water-insoluble matter where relevant. For solution, add concentration, density and clarity. Put identical test methods and acceptance limits in the quotation and purchase order. -
Q:
What handling and safety points apply to Sodium Thiocyanate?
A: Keep thiocyanate materials away from strong acids, strong bases and oxidizing agents because harmful decomposition gases can form. Store solid material dry and avoid dust generation, and confirm local exposure, waste and transport controls before transfer or blending. -
Q:
What should be confirmed before bulk or packaged Sodium Thiocyanate delivery?
A: Confirm moisture-resistant bags or drums for solid material, or compatible IBC or tank construction for solution, together with net quantity, seal condition, sampling and unloading arrangements. State intended use and the required solid form or solution concentration.
