1-Chloro-1-phenyl-propan-2-one CAS 4773-35-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-1-phenyl-propan-2-one.

1-Chloro-1-phenyl-propan-2-one (CAS 4773-35-7), molecular formula C12H10BrO4P and molecular weight 329.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Chloro-1-phenyl-propan-2-one (C12H10BrO4P) is characterized by a phosphate ester group, 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 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.
