Pharmaceutical Testing Reference Mterials

Pharmaceutical Reference Materials (PRMs) refer to substances with defined characteristic values used for calibrating instruments, evaluating measurement methods, or assigning values to tested pharmaceuticals in physical/chemical tests and biological assays specified by pharmacopoeial standards. These include reference standards, comparators, herbal reference materials, and reference preparations.

Hengyuan Fine Chemical specializes in providing cost-effective reference material solutions for pharmaceutical quality control, encompassing:

Drug testing reference standards
Pharmaceutical impurity reference standards
NIFDC-certified reference materials
