(R)​-3,​3'-​Bis(4-​chlorophenyl)​-​5,​5',​6,​6',​7,​7',​8,​8'-​octahydro-[1,​1'-​binaphthalene]​-​2,​2'-​diol CAS 915038-18-5 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 (R)​-3,​3'-​Bis(4-​chlorophenyl)​-​5,​5',​6,​6',​7,​7',​8,​8'-​octahydro-[1,​1'-​binaphthalene]​-​2,​2'-​diol.

CATO supplies (R)​-3,​3'-​Bis(4-​chlorophenyl)​-​5,​5',​6,​6',​7,​7',​8,​8'-​octahydro-[1,​1'-​binaphthalene]​-​2,​2'-​diol (CAS 915038-18-5), a certified reference material (molecular formula C32H28Cl2O2, MW 515.47 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, (R)​-3,​3'-​Bis(4-​chlorophenyl)​-​5,​5',​6,​6',​7,​7',​8,​8'-​octahydro-[1,​1'-​binaphthalene]​-​2,​2'-​diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 515.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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), (R)​-3,​3'-​Bis(4-​chlorophenyl)​-​5,​5',​6,​6',​7,​7',​8,​8'-​octahydro-[1,​1'-​binaphthalene]​-​2,​2'-​diol 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.
