Chemical Structure

1-(4-Chloro-2-fluorophenyl)pentan-1-one CAS 1343879-99-1 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-(4-Chloro-2-fluorophenyl)pentan-1-one.

CATO supplies 1-(4-Chloro-2-fluorophenyl)pentan-1-one (CAS 1343879-99-1), a certified reference material (molecular formula C11H12ClFO, MW 214.66 g/mol) for analytical method development and quality control.

Structurally, 1-(4-Chloro-2-fluorophenyl)pentan-1-one (C11H12ClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 214.66 g/mol, it falls into the medium-molecular-weight range. 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.

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.
