Chemical Structure

DL-Malic Acid CAS 6915-15-7 chemical structure

Description

The occurrence of DL-Malic Acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies DL-Malic Acid (CAS 6915-15-7), a certified reference material (molecular formula C4H6O5, MW 134.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H6O5, DL-Malic Acid contains a carbohydrate-derived structure; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 134.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
