Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.70 g/mol gives 5-Chloro-1-(2-methoxyphenyl)pentan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Chloro-1-(2-methoxyphenyl)pentan-1-one (CAS 43228-96-2), a certified reference material (molecular formula C12H15ClO2, MW 226.70 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H15ClO2, 5-Chloro-1-(2-methoxyphenyl)pentan-1-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
