Chemical Structure

Phosphate-citrate buffer CAS 934005-10-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 311.09 g/mol gives Phosphate-citrate buffer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Phosphate-citrate buffer (CAS 934005-10-4), a certified reference material (molecular formula C6H8O7HO4PNa, MW 311.09 g/mol) for analytical method development and quality control.

The molecular framework of Phosphate-citrate buffer (C6H8O7HO4PNa) is characterized by a carbohydrate-derived structure, a phosphate ester group. 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.

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.
