Triisopropylphosphine oxide CAS 17513-58-5 chemical structure

Description

CATO manufactures Triisopropylphosphine oxide 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.

Triisopropylphosphine oxide (CAS 17513-58-5) is a high-purity analytical reference standard with the molecular formula C9H21OP and a molecular weight of 176.24 g/mol.

The molecular framework of Triisopropylphosphine oxide (C9H21OP) is characterized by organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
