4-Ethyl-2-methylbenzoic acid CAS 190367-29-4

Description

Compared with other compounds in its class, the molecular weight of 164.20 g/mol gives 4-Ethyl-2-methylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Ethyl-2-methylbenzoic acid (CAS 190367-29-4) is a high-purity analytical reference standard with the molecular formula C10H12O2 and a molecular weight of 164.20 g/mol.

Structurally, 4-Ethyl-2-methylbenzoic acid (C10H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 164.20 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
