3-diphenylphosphanylpropane-1-sulfonic acid CAS 118516-47-5

Description

The occurrence of 3-diphenylphosphanylpropane-1-sulfonic acid is closely related to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-diphenylphosphanylpropane-1-sulfonic acid (CAS 118516-47-5), a certified reference material (molecular formula C15H29O3PS, MW 320.43 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-diphenylphosphanylpropane-1-sulfonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-diphenylphosphanylpropane-1-sulfonic acid 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.
