1-(3-Chloro-4-methylphenyl)butan-1-one CAS 1268091-22-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Chloro-4-methylphenyl)butan-1-one.

1-(3-Chloro-4-methylphenyl)butan-1-one (CAS 1268091-22-0) is a high-purity analytical reference standard with the molecular formula C11H13ClO and a molecular weight of 196.67 g/mol.

Structurally, 1-(3-Chloro-4-methylphenyl)butan-1-one (C11H13ClO) contains a hydroxyl group, an ether linkage, 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 196.67 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.

As a certified reference material (CRM), 1-(3-Chloro-4-methylphenyl)butan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
