Methyl 3-chloro-4-ethoxybenzoate CAS 192512-43-9

Description

Compared with other compounds in its class, the molecular weight of 214.65 g/mol gives Methyl 3-chloro-4-ethoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 3-chloro-4-ethoxybenzoate (CAS 192512-43-9), molecular formula C10H11ClO3 and molecular weight 214.65 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Methyl 3-chloro-4-ethoxybenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
