Chemical Structure

Trimethylphosphine oxide CAS 676-96-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Trimethylphosphine oxide (CAS 676-96-0) is a high-purity analytical reference standard with the molecular formula C3H9OP and a molecular weight of 92.08 g/mol.

The molecular framework of Trimethylphosphine oxide (C3H9OP) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
