Cholesterol Related Compounds & Impurities

Cholesterol is the principal endogenous sterol, serving as a cell-membrane structural component and precursor of steroid hormones, bile acids and vitamin D, used as a liposomal formulation stabiliser.

Simson Pharma Limited along with its subsidiary offices Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) is a trusted manufacturer and supplier of high-quality pharmaceutical reference standards, offering a comprehensive portfolio of Cholesterol reference standards, pharmacopeial and non-pharmacopeial Cholesterol impurities, related compounds, related substances, metabolites, stable isotope-labelled compounds, deuterium labelled compounds and nitrosamine (N-NO) reference standards.

These materials support pharmaceutical research and development, product development, ANDA and DMF submissions, quality control (QC), analytical method development and validation, stability studies, impurity identification, and genotoxic impurity assessment.

Our Cholesterol-related reference standards are thoroughly characterized using advanced analytical techniques and are supplied with comprehensive Certificates of Analysis (COA) and supporting analytical data from our USFDA certified, ISO 17025 and ISO 17034 accredited Lab, to meet global regulatory expectations.
