Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Bromoisobutyryloxy)ethyl methacrylate 2-Methacryloxyethyl 2 inverted exclamation marka-bromoisobutyrate 2-Methylacrylic acid 2-(2-bromo-2-methylpropionyloxy) ethyl ester 213453-08-8 BIEM.

2-(2-Bromoisobutyryloxy)ethyl methacrylate 2-Methacryloxyethyl 2 inverted exclamation marka-bromoisobutyrate 2-Methylacrylic acid 2-(2-bromo-2-methylpropionyloxy) ethyl ester 213453-08-8 BIEM (CAS 213453-08-8) is a high-purity analytical reference standard with the molecular formula C10H15BrO4 and a molecular weight of 279.13 g/mol.

The molecular framework of 2-(2-Bromoisobutyryloxy)ethyl methacrylate 2-Methacryloxyethyl 2 inverted exclamation marka-bromoisobutyrate 2-Methylacrylic acid 2-(2-bromo-2-methylpropionyloxy) ethyl ester 213453-08-8 BIEM (C10H15BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 2-(2-Bromoisobutyryloxy)ethyl methacrylate 2-Methacryloxyethyl 2 inverted exclamation marka-bromoisobutyrate 2-Methylacrylic acid 2-(2-bromo-2-methylpropionyloxy) ethyl ester 213453-08-8 BIEM 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.
