Chemical Structure

Shikimate-3-phosphate Trisodium Salt CAS 143393-03-7 chemical structure

Description

Shikimate-3-phosphate Trisodium Salt (CAS 143393-03-7), molecular formula C7H8O8PNa and molecular weight 274.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Shikimate-3-phosphate Trisodium Salt (C7H8O8PNa) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
