Ethyl 4-bromo-2-isopropylbenzoate CAS 2404733-86-2

Description

Compared with other compounds in its class, the molecular weight of 271.15 g/mol gives Ethyl 4-bromo-2-isopropylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 4-bromo-2-isopropylbenzoate (CAS 2404733-86-2), molecular formula C12H15BrO2 and molecular weight 271.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 4-bromo-2-isopropylbenzoate (C12H15BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
