5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol CAS 39648-74-3 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 5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol.

5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol (CAS 39648-74-3), molecular formula C20H22O2 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol (C20H22O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 294.39 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthol 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.
