Reference Standard

With more than 300 commercial reference standards in stock, Purisys provides structural elucidation and comprehensive characterization data for your development and commercial requirements in support of regulatory filings and drug product releases.

Purisys has a specialized process to support rapid development and qualification of standards. We can support you by providing custom synthesis of degradation products, metabolites, and other unique impurities. We can also provide investigative services including identification, standard preparation, and relative response factor determination of impurities found in dosage forms.

We ship reference standards to more than 40 countries on six continents. We can manufacture, store, and distribute a broad array of controlled substances, and we have two global ISO certifications: ISO 7025 (Testing and Calibration Laboratories) and ISO 17034 (Reference APIs Producers). These certifications ensure the quality of our services and the purity and potency of the products we make.
