Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pregna-1,4-diene-3-one, 17,20-dihydroxy-6-methylene.
CATO supplies Pregna-1,4-diene-3-one, 17,20-dihydroxy-6-methylene (CAS 1204325-02-9), a certified reference material (molecular formula C22H30O3, MW 342.47 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, Pregna-1,4-diene-3-one, 17,20-dihydroxy-6-methylene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.47 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).
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 Pregna-1,4-diene-3-one, 17,20-dihydroxy-6-methylene 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.
