We are one of the world leading companies in manufacturing pharmaceutical standards, including stable-isotope labeled internal standards, metabolites, degradation compounds/impurities, and inhibitor reference compounds. Our products are widely used in Bioanalysis (BA) for preclinical/early stage clinical studies and Bioequivalence (BE) studies for generic drug development. We also provide stable-isotope labeled reference standards for environmental and agricultural uses. Our utmost goal is to provide high-quality, low-cost standard compounds and commercial non-available research chemicals to global pharmaceutical, biotechnological, clinical and bio-analytical companies. Yours truly,
