Chemical Structure

Di-tert-butyl 2-methylmalonate CAS 34812-95-8 chemical structure

Description

Di-tert-butyl 2-methylmalonate (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.

Di-tert-butyl 2-methylmalonate (CAS 34812-95-8) is a high-purity analytical reference standard with the molecular formula C12H22O4 and a molecular weight of 230.30 g/mol.

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

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.
