(1S,1'S,2R,2'R)-1,1'-Di-tert-butyl-7,7'-dimethoxy-2,2',3,3'-tetrahydro-1H,1'H-2,2'-biphosphindole CAS 1477517-22-8

Description

CATO supplies (1S,1'S,2R,2'R)-1,1'-Di-tert-butyl-7,7'-dimethoxy-2,2',3,3'-tetrahydro-1H,1'H-2,2'-biphosphindole (CAS 1477517-22-8), a certified reference material (molecular formula C26H36O2P2, MW 442.51 g/mol) for analytical method development and quality control.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, (1S,1'S,2R,2'R)-1,1'-Di-tert-butyl-7,7'-dimethoxy-2,2',3,3'-tetrahydro-1H,1'H-2,2'-biphosphindole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.51 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), (1S,1'S,2R,2'R)-1,1'-Di-tert-butyl-7,7'-dimethoxy-2,2',3,3'-tetrahydro-1H,1'H-2,2'-biphosphindole 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.
