Chemical Structure

(3β)-26,27-Dinorcholest-5-en-24-yne-3,20-diol CAS 1397692-46-4 chemical structure

Description

As a certified reference material (CRM), (3β)-26,27-Dinorcholest-5-en-24-yne-3,20-diol 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.

(3β)-26,27-Dinorcholest-5-en-24-yne-3,20-diol (CAS 1397692-46-4), molecular formula C25H38O2 and molecular weight 370.57 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, (3β)-26,27-Dinorcholest-5-en-24-yne-3,20-diol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.57 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.
