Chemical Structure
Description
2-Bromo-4-butoxy-5-ethoxybenzaldehyde (CAS 832674-50-7), molecular formula C13H17BrO3 and molecular weight 301.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4-butoxy-5-ethoxybenzaldehyde (C13H17BrO3) 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 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.
CATO manufactures 2-Bromo-4-butoxy-5-ethoxybenzaldehyde 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.
