Chemical Structure
Description
CATO supplies 1-(2-Bromo-1-(sec-butoxy)ethyl)-4-chlorobenzene (CAS 21395-07-3), a certified reference material (molecular formula C12H16BrClO, MW 291.61 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Bromo-1-(sec-butoxy)ethyl)-4-chlorobenzene (C12H16BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/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. 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.
As a certified reference material (CRM), 1-(2-Bromo-1-(sec-butoxy)ethyl)-4-chlorobenzene 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.
