Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 639.09 g/mol gives Cholesteryl heptadecanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cholesteryl heptadecanoate (CAS 24365-37-5) is a high-purity analytical reference standard with the molecular formula C44H78O2 and a molecular weight of 639.09 g/mol.
Cholesteryl heptadecanoate (C44H78O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Cholesteryl heptadecanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
