Chemical Structure

(S)-4-(tert-Butoxy)-2-(tert-butyl)-4-oxobutanoic acid CAS 210048-06-9 chemical structure

Description

(S)-4-(tert-Butoxy)-2-(tert-butyl)-4-oxobutanoic acid (CAS 210048-06-9) is a high-purity analytical reference standard with the molecular formula C12H22O4 and a molecular weight of 230.30 g/mol.

(S)-4-(tert-Butoxy)-2-(tert-butyl)-4-oxobutanoic acid (C12H22O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
