Chemical Structure

Phosphoric acid, monoethyl ester, Sodium salt CAS 17323-83-0 chemical structure

Description

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.

Phosphoric acid, monoethyl ester, Sodium salt (CAS 17323-83-0), molecular formula C2H5O4PNa and molecular weight 147.02 g/mol, is a CATO reference standard with documented purity and traceability.

Phosphoric acid, monoethyl ester, Sodium salt (C2H5O4PNa) contains a phosphate ester group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
