Chemical Structure

(R)-2-methyl-4-nitrobutanoic acid CAS 88390-28-7 chemical structure

Description

(R)-2-methyl-4-nitrobutanoic acid (C5H9NO4) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies (R)-2-methyl-4-nitrobutanoic acid (CAS 88390-28-7), a certified reference material (molecular formula C5H9NO4, MW 147.13 g/mol) for analytical method development and quality control.

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.
