Tetramethylammonium dihydrogen phosphate CAS 40768-19-2

Description

Compared with other compounds in its class, the molecular weight of 171.13 g/mol gives Tetramethylammonium dihydrogen phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tetramethylammonium dihydrogen phosphate (CAS 40768-19-2) is a high-purity analytical reference standard with the molecular formula H2O4PC4H12N and a molecular weight of 171.13 g/mol.

The molecular framework of Tetramethylammonium dihydrogen phosphate (H2O4PC4H12N) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
