Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.58 g/mol gives 2-Bromo-N-(5-chloro-2,4-dimethoxyphenyl)propanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-N-(5-chloro-2,4-dimethoxyphenyl)propanamide (CAS 1119452-45-7), a certified reference material (molecular formula C11H13BrClNO3, MW 322.58 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 2-Bromo-N-(5-chloro-2,4-dimethoxyphenyl)propanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-N-(5-chloro-2,4-dimethoxyphenyl)propanamide 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.
