Sodium Thiocyanate (CAS 540-72-7): Comprehensive User Guide

1. Product Overview & Specifications

Chemical Profile

Sodium Thiocyanate (NaSCN), CAS 540-72-7, is a white crystalline compound with molecular weight 81.07 g/mol. Soluble in water and ethanol, it decomposes at 300°C.

Technical Specifications

Parameter Specification Thiocyanate Alternatives
Purity ≥99.0% KSCN (98.5%), NH4SCN (97%)
pH (5% sol.) 6.0-7.5 KSCN: 5.5-8.0
Heavy Metals ≤10ppm Industry Std: ≤15ppm

2. Key Applications & Industrial Uses

Core Functional Roles

  • Textile Manufacturing: Fiber solvent in acrylic fiber production
  • Chemical Synthesis: Catalyst in polymerization reactions
  • Pharmaceuticals: Intermediate in antihypertensive drug synthesis
  • Metal Treatment: Corrosion inhibitor in electroplating baths

Performance Advantages

  • 35% higher solubility than ammonium thiocyanate
  • Superior thermal stability (stable up to 250°C)
  • Low chloride content (<0.005%) prevents equipment corrosion

3. Practical Implementation Scenarios

Optimized Usage Protocols

Polymer Production: Use 0.5-1.2% NaSCN as chain transfer agent in ABS resin synthesis

Textile Processing: 15-20% aqueous solution for acrylic fiber spinning

Safety Handling

  • PPE Requirement: Nitrile gloves + Chemical goggles
  • Storage: Maintain RH <45% in polyethylene containers

4. Verified Customer Case Studies
