Impurities/Metabolites/Intermediates

Pharmaceutical impurities may have a significant influence on the effects of a drug or may cause unwanted side-effects. Guidelines and limits for many impurities are described in the pharmacopeia monographs.
Our expertise lies in providing unique combination of capabilities to Pharmaceutical industry for Impurity standards, Metabolites, Intermediates, API Impurity Reference Standards, Process Impurity and Degradation Impurity.
PureSynth customised pharmaceutical impurities on request. Supply of impurities in quantities from milligram to gram and each impurity is supported with detailed certificate of analysis also provided additional documentation on request. Assistance in finding the right material to suit your analysis.
