Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-(2-methylpropyl)-Benzoic Acid Methyl Ester.
4-Bromo-2-(2-methylpropyl)-Benzoic Acid Methyl Ester (CAS 643094-18-2) is a high-purity analytical reference standard with the molecular formula C12H15BrO2 and a molecular weight of 271.15 g/mol.
The molecular framework of 4-Bromo-2-(2-methylpropyl)-Benzoic Acid Methyl Ester (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.
As a certified reference material (CRM), 4-Bromo-2-(2-methylpropyl)-Benzoic Acid Methyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
