p-Methylphosphonic Acid- CAS 106976-96-9 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.

p-Methylphosphonic Acid- (CAS 106976-96-9), molecular formula [13C]H5O3P and molecular weight 97.02 g/mol, is a CATO reference standard with documented purity and traceability.

p-Methylphosphonic Acid- ([13C]H5O3P) contains a phosphonate group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
