Chemical Structure

Dodecyldiphenylphosphineoxide CAS 90177-29-0 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.

Dodecyldiphenylphosphineoxide (CAS 90177-29-0), molecular formula C24H35OP and molecular weight 370.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, Dodecyldiphenylphosphineoxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Dodecyldiphenylphosphineoxide 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.
