Chemical Structure
Description
9-chloro-7-(nonan-5-yl)-1,2,3,4,4a,9b-hexahydrodibenzo[b,d]furan-4-ol (CAS CATO-C3D-262397), molecular formula C21H31ClO2 and molecular weight 350.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-chloro-7-(nonan-5-yl)-1,2,3,4,4a,9b-hexahydrodibenzo[b,d]furan-4-ol (C21H31ClO2) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 9-chloro-7-(nonan-5-yl)-1,2,3,4,4a,9b-hexahydrodibenzo[b,d]furan-4-ol 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.
