Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,9-Dimethyl-4,5-bis(di-t-butylphosphino)xanthene 856405-77-1 4,5-BIS(DI-TERT-BUTYLPHOSPHINO)-9,9-DIMETHYLXANTHENE;9,9-DIMETHYL-4,5-BIS(DI-T-BUTYLPHOSPHINO)XANTHENE;9,9-DIMETHYL-4,5-BIS(DI-TERT-BUTYLPHOSPHINO)XANTHENE;T-BU-XANTPHOS SC11340.

CATO supplies 9,9-Dimethyl-4,5-bis(di-t-butylphosphino)xanthene 856405-77-1 4,5-BIS(DI-TERT-BUTYLPHOSPHINO)-9,9-DIMETHYLXANTHENE;9,9-DIMETHYL-4,5-BIS(DI-T-BUTYLPHOSPHINO)XANTHENE;9,9-DIMETHYL-4,5-BIS(DI-TERT-BUTYLPHOSPHINO)XANTHENE;T-BU-XANTPHOS SC11340 (CAS 856405-77-1), a certified reference material (molecular formula C31H60OP2, MW 510.76 g/mol) for analytical method development and quality control.

Structurally, 9,9-Dimethyl-4,5-bis(di-t-butylphosphino)xanthene 856405-77-1 4,5-BIS(DI-TERT-BUTYLPHOSPHINO)-9,9-DIMETHYLXANTHENE;9,9-DIMETHYL-4,5-BIS(DI-T-BUTYLPHOSPHINO)XANTHENE;9,9-DIMETHYL-4,5-BIS(DI-TERT-BUTYLPHOSPHINO)XANTHENE;T-BU-XANTPHOS SC11340 (C31H60OP2) contains organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 510.76 g/mol, it falls into the moderately-high-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), 9,9-Dimethyl-4,5-bis(di-t-butylphosphino)xanthene 856405-77-1 4,5-BIS(DI-TERT-BUTYLPHOSPHINO)-9,9-DIMETHYLXANTHENE;9,9-DIMETHYL-4,5-BIS(DI-T-BUTYLPHOSPHINO)XANTHENE;9,9-DIMETHYL-4,5-BIS(DI-TERT-BUTYLPHOSPHINO)XANTHENE;T-BU-XANTPHOS SC11340 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.
