Chemical Structure

Pregnenolon CAS 566-63-2 chemical structure

Description

Pregnenolon (CAS 566-63-2), molecular formula C21H32O2 and molecular weight 316.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, Pregnenolon is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Pregnenolon 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.
