FAQ
Is Sodium Thiocyanate hygroscopic, and how to avoid agglomeration during storage?
Yes, Sodium Thiocyanate is highly hygroscopic. To avoid agglomeration, it should be stored in a cool, dry, well-ventilated warehouse, sealed tightly in moisture-proof packaging, and kept away from humid environments and water sources.
Can Sodium Thiocyanate be used in food-grade applications for export?
Yes, food-grade Sodium Thiocyanate meets international food safety standards, with strict limits on impurities and heavy metals. It can be used in food processing after passing relevant inspections, suitable for export food production.
What is the difference between industrial-grade and pharmaceutical-grade Sodium Thiocyanate?
The main difference lies in the purity and impurity content: pharmaceutical-grade Sodium Thiocyanate has higher purity (usually ≥ 99.0%) and stricter control over harmful impurities, suitable for pharmaceutical synthesis; industrial-grade is mainly used in industrial fields with relatively loose purity requirements.
