CATO supplies 2-Methoxysuccinic acid (CAS 1726-80-3), a certified reference material (molecular formula C5H8O5, MW 148.11 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, 2-Methoxysuccinic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
