Chemical Structure
Description
1-(5-Chloro-2-methylphenyl)propan-1-one (CAS 1193779-97-3), molecular formula C10H11ClO and molecular weight 182.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Chloro-2-methylphenyl)propan-1-one (C10H11ClO) is characterized by a hydroxyl group, an ether linkage, chlorine 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 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.
