1-[1-(3-bromophenyl)-2,5-dimethyl-1H-pyrrol-3-yl]-2-chloroethanone CAS 757192-83-9

Description

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.

1-[1-(3-bromophenyl)-2,5-dimethyl-1H-pyrrol-3-yl]-2-chloroethanone (CAS 757192-83-9) is a high-purity analytical reference standard with the molecular formula C14H13BrClNO and a molecular weight of 326.62 g/mol.

1-[1-(3-bromophenyl)-2,5-dimethyl-1H-pyrrol-3-yl]-2-chloroethanone (C14H13BrClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.

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.
