Description

CATO manufactures Bis(2-ethylhexyl)phosphinic acid, 95% 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.

Bis(2-ethylhexyl)phosphinic acid, 95% (CAS 13525-99-0), molecular formula C16H35O2P and molecular weight 290.42 g/mol, is a CATO reference standard with documented purity and traceability.

Bis(2-ethylhexyl)phosphinic acid, 95% (C16H35O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
