trans-2-[2-(3-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid CAS 733740-61-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including trans-2-[2-(3-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid.

trans-2-[2-(3-Bromophenyl)-2-oxoethyl]-cyclopentane-1-carboxylic acid (CAS 733740-61-9) 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 trans-2-[2-(3-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
