Chemical Structure
Description
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (Hydroxymethyl)diphenylphosphine oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(Hydroxymethyl)diphenylphosphine oxide (CAS 884-74-2), molecular formula C13H13O2P and molecular weight 232.21 g/mol, is a CATO reference standard with documented purity and traceability.
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), (Hydroxymethyl)diphenylphosphine oxide 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.
