Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 214.65 g/mol gives 2-Chloro-1-(3,5-dimethoxyphenyl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloro-1-(3,5-dimethoxyphenyl)ethan-1-one (CAS 72612-04-5), a certified reference material (molecular formula C10H11ClO3, MW 214.65 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-Chloro-1-(3,5-dimethoxyphenyl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.65 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-Chloro-1-(3,5-dimethoxyphenyl)ethan-1-one 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.
