Pharmaceutical Reference Standards

Pharmaceutical reference standards for drug testing, development and registration: active ingredients, related impurities, degradation products and isotope-labelled standards for use as internal standards in LC-MS/MS.

The range follows pharmacopoeial requirements and ICH impurity guidelines, where correctly identifying an impurity matters as much as quantifying the active ingredient. Products from TRC and LGC; each lot ships with a certificate of analysis stating purity and storage conditions.
