CUSTOM SYNTHESIS OF IMPURITIES

We have synthesized more than 15,000 impurities as of date. VEEPRHO can provide fast and reliable service for a custom synthesis of impurities, based on the following information:

1) Structure of the impurity.
2) Name of the parent drug.
3) Required quantity.
4) CAS No. of the impurity (if available)

Please contact us if you require custom synthesis and we would be glad to help you with our custom synthesis service.

IMPURITY ISOLATION AND PURIFICATION

Isolation and Purification of Known and Unknown Impurities from milligram to gram scale, which is performed by our talented team of scientists who always provide high-quality products. We have executed the most critical isolation and purification projects from the drug product, API, and structure elucidation of the appropriate project.

Structure Interpretation Studies for spatial heterogeneity identifications, we conduct these studies on reactants, products, or conditions by using 2-D NMR techniques. These studies involve homonuclear correlation experiments like NOESY, DQF-COSY, TOCSY, and ROESY and heteronuclear correlation experiments like HMQC, HSQC, and HMBC.
