Chemical Structure

2-(4-Bromophenyl)-2-methylpropanoyl chloride CAS 1040860-77-2 chemical structure

Description

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.

2-(4-Bromophenyl)-2-methylpropanoyl chloride (CAS 1040860-77-2), molecular formula C10H10BrClO and molecular weight 261.54 g/mol, is a CATO reference standard with documented purity and traceability.

2-(4-Bromophenyl)-2-methylpropanoyl chloride (C10H10BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
