Chemical Structure

Methylmalonic Acid CAS 516-05-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 118.09 g/mol gives Methylmalonic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methylmalonic Acid (CAS 516-05-2), a certified reference material (molecular formula C4H6O4, MW 118.09 g/mol) for analytical method development and quality control.

Methylmalonic Acid (C4H6O4) contains a carbohydrate-derived structure. 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.

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.
