Chemical Structure

4-(tert-butoxy)-2-methyl-4-oxobutanoic acid CAS 76904-18-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4-(tert-butoxy)-2-methyl-4-oxobutanoic acid (CAS 76904-18-2), a certified reference material (molecular formula C9H16O4, MW 188.22 g/mol) for analytical method development and quality control.

The molecular framework of 4-(tert-butoxy)-2-methyl-4-oxobutanoic acid (C9H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
