The product uses ultra-high purification technology and is packaged in a 10,000-level clean workshop. The microbial content and endotoxin content strictly meet pharmaceutical production standards. It can replace highly toxic dimethyl sulfate as a methylation reagent, with by-products of carbon dioxide and methanol, no toxic residues, which greatly reduces the impurity content in active pharmaceutical ingredients and improves drug safety. It also has excellent solubility, can dissolve most pharmaceutical intermediates, and adapts to multiple synthesis reaction conditions.
The product has a purity of ≥99.98%, residual solvent ≤20ppm, total microbial count ≤10 CFU/g, endotoxin ≤0.5 EU/ml, heavy metal ≤0.01ppm, density of 1.069±0.002 g/cm³ at 25℃, colorless and transparent liquid appearance, transmittance ≥99% at 400nm wavelength. The packaging uses clean grade sealed barrels, and each batch of products is attached with USP test report, microbial test report and clean workshop certification documents.
It is used for the synthesis of antidepressant active pharmaceutical ingredients, methylation reaction of antibiotic intermediates, esterification synthesis of cardiovascular drugs, and production of vaccine excipients. It can adapt to the GMP production requirements of domestic and foreign pharmaceutical enterprises, helping pharmaceutical enterprises pass on-site audits by FDA and NMPA, and improving the quality compliance of active pharmaceutical ingredients.
