Chemical Structure

Epicholesterol CAS 474-77-1 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, Epicholesterol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Epicholesterol (CAS 474-77-1), molecular formula C27H46O and molecular weight 386.66 g/mol, is a CATO reference standard with documented purity and traceability.

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 Epicholesterol 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.
