Chemical Structure

L-Malic Acid Disodium Salt Monohydrate CAS 207511-06-6 chemical structure

Description

The molecular framework of L-Malic Acid Disodium Salt Monohydrate (C4H4O5NaH2O) is characterized by a carbohydrate-derived structure. 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.

L-Malic Acid Disodium Salt Monohydrate (CAS 207511-06-6) is a high-purity analytical reference standard with the molecular formula C4H4O5NaH2O and a molecular weight of 173.08 g/mol.

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.
