Chemical Structure

diisooctylthiophosphinic acid CAS 132767-86-3 chemical structure

Description

CATO supplies diisooctylthiophosphinic acid (CAS 132767-86-3), a certified reference material (molecular formula C16H35OPS, MW 306.49 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H35OPS, diisooctylthiophosphinic acid contains sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 306.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 diisooctylthiophosphinic acid 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.
