Chemical Structure
Description
The occurrence of 3-Bromo-5-methoxy-4-propoxybenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-5-methoxy-4-propoxybenzaldehyde (CAS 91335-52-3) is a high-purity analytical reference standard with the molecular formula C11H13BrO3 and a molecular weight of 273.12 g/mol.
The molecular framework of 3-Bromo-5-methoxy-4-propoxybenzaldehyde (C11H13BrO3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
