609-14-3 NE9WOZ20JE Ethyl 2-methyl-3-oxobutanoate Acetoacetic acid, 2-methyl-, ethyl ester (8CI) Butanoic acid, 2-methyl-3-oxo-, ethyl ester Ethyl 2-methylacetoacetate AI3-05606 EINECS 210-179-9 Ethyl alpha-acetylpropionate Ethyl 2-acetylpropionate Ethyl methylacetoacetate Ethyl alpha-methylacetylacetate Ethyl 2-methyl-3-oxobutyrate alpha-Methylacetoacetic ester NSC 1102 UNII-NE9WOZ20JE (CAS 609-14-3) is a high-purity analytical reference standard with the molecular formula C7H12O3 and a molecular weight of 144.17 g/mol.

609-14-3 NE9WOZ20JE Ethyl 2-methyl-3-oxobutanoate Acetoacetic acid, 2-methyl-, ethyl ester (8CI) Butanoic acid, 2-methyl-3-oxo-, ethyl ester Ethyl 2-methylacetoacetate AI3-05606 EINECS 210-179-9 Ethyl alpha-acetylpropionate Ethyl 2-acetylpropionate Ethyl methylacetoacetate Ethyl alpha-methylacetylacetate Ethyl 2-methyl-3-oxobutyrate alpha-Methylacetoacetic ester NSC 1102 UNII-NE9WOZ20JE (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.

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.
