Chemical Structure

methyl 4-(3,4-dichlorophenyl)butanoate CAS 1368308-27-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 247.12 g/mol gives methyl 4-(3,4-dichlorophenyl)butanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

methyl 4-(3,4-dichlorophenyl)butanoate (CAS 1368308-27-3), molecular formula C11H12Cl2O2 and molecular weight 247.12 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 4-(3,4-dichlorophenyl)butanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
