Chemical Structure

Dunnianol CAS 139726-29-7 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 Dunnianol.

Dunnianol (CAS 139726-29-7) is a high-purity analytical reference standard with the molecular formula C27H26O3 and a molecular weight of 398.49 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Dunnianol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.49 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.

As a certified reference material (CRM), Dunnianol 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.
