Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-2-chloro-4-ethoxy-3-methylbenzene.
1-Bromo-2-chloro-4-ethoxy-3-methylbenzene (CAS 2379322-33-3) is a high-purity analytical reference standard with the molecular formula C9H10BrClO and a molecular weight of 249.53 g/mol.
The molecular framework of 1-Bromo-2-chloro-4-ethoxy-3-methylbenzene (C9H10BrClO) 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 the polarity and ionization state of its functional groups, 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.
CATO manufactures 1-Bromo-2-chloro-4-ethoxy-3-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
