Quality Control

Our 4-Mercapto-4-Methylpentan-2-One is produced under strict quality management systems. Each batch undergoes rigorous analytical testing including GC, HPLC, and organoleptic evaluation to ensure high purity, consistent olfactory profile, and compliance with industry standards such as FEMA and IFRA. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (nitrogen or argon) to minimize oxidation and volatility. Keep away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed after each use.
