For professionals in the flavor and fragrance industries, the quality of raw materials directly dictates the success of their final products. Propyl Disulfide (CAS 629-19-6), a key sulfurous aroma chemical, is no exception. When you need to buy this compound, understanding how to assess quality and select a reliable manufacturer is crucial for achieving consistent results and cost-effectiveness.

The primary indicator of Propyl Disulfide quality is its purity, often specified as an assay of ≥99.0%.

  • Production Capacity and Reliability: Confirm they can meet your volume requirements and delivery schedules.
  • Pricing and Value: Compare quotes from multiple suppliers to secure competitive pricing.
  • Customer Service and Technical Support: A responsive and knowledgeable supplier can be invaluable.

By diligently researching and vetting potential suppliers, flavor and fragrance houses can secure a dependable source of high-quality Propyl Disulfide.
