Chemical Structure

rel-(2S,3R)-2-Amino-3-methylsuccinic acid CAS 1114-07-4 chemical structure

Description

CATO supplies rel-(2S,3R)-2-Amino-3-methylsuccinic acid (CAS 1114-07-4), a certified reference material (molecular formula C5H9NO4, MW 147.13 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, an amide group, rel-(2S,3R)-2-Amino-3-methylsuccinic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
