Chemical Structure
Description
3-Ketovaleric Acid Ethyl Ester 3-Oxovaleric Acid Ethyl Ester 4949-44-4 Ethyl 3-Oxopentanoate Ethyl 3-Oxovalerate Ethyl Propionylacetate K0031 Propionylacetic Acid Ethyl Ester (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.
3-Ketovaleric Acid Ethyl Ester 3-Oxovaleric Acid Ethyl Ester 4949-44-4 Ethyl 3-Oxopentanoate Ethyl 3-Oxovalerate Ethyl Propionylacetate K0031 Propionylacetic Acid Ethyl Ester (CAS 4949-44-4) is a high-purity analytical reference standard with the molecular formula C7H12O3 and a molecular weight of 144.17 g/mol.
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.
