Chemical Structure
Description
The occurrence of (1R,2S)-2-(2-(2-bromophenyl)-2-oxoethyl)cyclopentane-1-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1R,2S)-2-(2-(2-bromophenyl)-2-oxoethyl)cyclopentane-1-carboxylic acid (CAS 733740-67-5) is a high-purity analytical reference standard with the molecular formula C14H15BrO3 and a molecular weight of 311.17 g/mol.
The molecular framework of (1R,2S)-2-(2-(2-bromophenyl)-2-oxoethyl)cyclopentane-1-carboxylic acid (C14H15BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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.
