Chemical Structure

Methyl 2-ethylbutanoate CAS 816-11-5 chemical structure

Description

The occurrence of Methyl 2-ethylbutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2-ethylbutanoate (CAS 816-11-5), molecular formula C7H14O2 and molecular weight 130.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 2-ethylbutanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
