Description

As a certified reference material (CRM), (4S,5S,6S,7R)-5,7-Dimethoxy-4,6-dimethyl-8-(phenylmethoxy)-1-octanol 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.

CATO supplies (4S,5S,6S,7R)-5,7-Dimethoxy-4,6-dimethyl-8-(phenylmethoxy)-1-octanol (CAS 276690-17-6), a certified reference material (molecular formula C19H32O4, MW 324.45 g/mol) for analytical method development and quality control.

Structurally, (4S,5S,6S,7R)-5,7-Dimethoxy-4,6-dimethyl-8-(phenylmethoxy)-1-octanol (C19H32O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 324.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
