Bis(3,5-dimethylphenyl)phosphinicacid CAS 137219-82-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis(3,5-dimethylphenyl)phosphinicacid.

Bis(3,5-dimethylphenyl)phosphinicacid (CAS 137219-82-0), molecular formula C16H19O2P and molecular weight 274.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H19O2P, Bis(3,5-dimethylphenyl)phosphinicacid contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Bis(3,5-dimethylphenyl)phosphinicacid 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.
