Chemical Structure

10-Beta-Hydroxyestr-4-Ene-3,17-Dione CAS 5189-96-8 chemical structure

Description

As a certified reference material (CRM), 10-Beta-Hydroxyestr-4-Ene-3,17-Dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

10-Beta-Hydroxyestr-4-Ene-3,17-Dione (CAS 5189-96-8), molecular formula C18H24O3 and molecular weight 288.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 10-Beta-Hydroxyestr-4-Ene-3,17-Dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.38 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.
