Core Value
In the production of APIs, trace impurities can have a significant impact on the safety and efficacy of the final drug. Aluminum Chloride Hexahydrate, as a key catalyst and raw material in pharmaceutical intermediate synthesis, directly transmits its own impurity levels to downstream products. Nantong Mengya New Materials Technology Co., Ltd. places impurity control at the core of product quality, committed to providing customers with high‑purity Aluminum Chloride Hexahydrate.
Key Impurity Control Specifications
Impurity Control Limit Impact on API Quality
Iron (Fe) < 0.05% Excessive iron causes abnormal API coloration and catalytic side reactions
Heavy Metals (as Pb) < 0.02% Residual heavy metals may affect API safety evaluation
Water Insolubles < 0.10% Affects reaction system homogeneity and filtration efficiency
Purification Process Highlights
Multi‑stage recrystallization – effectively removes metal ions such as Fe, Cu, and Zn
Negative‑pressure freeze…
