Chemical Structure

2,2-Dimethyl-4-oxopentanoic acid CAS 470-49-5 chemical structure

Description

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.

CATO supplies 2,2-Dimethyl-4-oxopentanoic acid (CAS 470-49-5), a certified reference material (molecular formula C7H12O3, MW 144.17 g/mol) for analytical method development and quality control.

2,2-Dimethyl-4-oxopentanoic acid (C7H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
