Potassium diphenylphosphate solution CAS 15475-27-1

Description

Potassium diphenylphosphate solution (CAS 15475-27-1), molecular formula C12H22KP and molecular weight 236.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, Potassium diphenylphosphate solution is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.38 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.

CATO manufactures Potassium diphenylphosphate solution under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
