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 (3-Bromo-4-((3,4-dichlorobenzyl)oxy)-5-ethoxyphenyl)methanol.
CATO supplies (3-Bromo-4-((3,4-dichlorobenzyl)oxy)-5-ethoxyphenyl)methanol (CAS 678551-57-0), a certified reference material (molecular formula C16H15BrCl2O3, MW 406.10 g/mol) for analytical method development and quality control.
Structurally, (3-Bromo-4-((3,4-dichlorobenzyl)oxy)-5-ethoxyphenyl)methanol (C16H15BrCl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 406.10 g/mol, it falls into the moderately-high-molecular-weight range. 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 (3-Bromo-4-((3,4-dichlorobenzyl)oxy)-5-ethoxyphenyl)methanol 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.
