Chemical Structure

2-diphenylphosphanylethanesulfonic acid CAS 118516-46-4 chemical structure

Description

Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-diphenylphosphanylethanesulfonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.40 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.

2-diphenylphosphanylethanesulfonic acid (CAS 118516-46-4), molecular formula C14H27O3PS and molecular weight 306.40 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-diphenylphosphanylethanesulfonic 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.
