Chemical Structure

ethyl 2-hydroxy-2-methylbutanoate CAS 77-70-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 146.18 g/mol gives ethyl 2-hydroxy-2-methylbutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

ethyl 2-hydroxy-2-methylbutanoate (CAS 77-70-3), molecular formula C7H14O3 and molecular weight 146.18 g/mol, is a CATO reference standard with documented purity and traceability.

ethyl 2-hydroxy-2-methylbutanoate (C7H14O3) 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.

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.
