Chemical Structure

tert-Butyl(Phenyl)phosphine oxide CAS 6057-79-0 chemical structure

Description

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.

tert-Butyl(Phenyl)phosphine oxide (CAS 6057-79-0), molecular formula C10H15OP and molecular weight 182.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, tert-Butyl(Phenyl)phosphine oxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures tert-Butyl(Phenyl)phosphine 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.
