Chemical Structure

Bephenium CAS 7181-73-9 chemical structure

Description

As a certified reference material (CRM), Bephenium 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.

Bephenium (CAS 7181-73-9) is a high-purity analytical reference standard with the molecular formula C17H22NO and a molecular weight of 256.36 g/mol.

Structurally, Bephenium (C17H22NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 256.36 g/mol, it falls into the medium-molecular-weight range. 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.
