Cholesterol

Cholesterol is the principal sterol of mammalian cell membranes and the biosynthetic precursor of all steroid hormones, bile acids and vitamin D, used as a pharmaceutical excipient in liposomal and lipid nanoparticle formulations and as a foundational reference compound in lipid analysis. Simson Pharma's Cholesterol reference standard supports identity and purity testing across these diverse analytical and formulation contexts.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Cholesterol Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
