Quality Control

Our 3-Chloro-4-(Methylthio)Aniline is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment. We adhere to cGMP principles where applicable to meet the stringent requirements of the pharmaceutical and agrochemical industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents, acids, and bases.
