Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 898761-48-3 4-Chloro-1-(3,4-difluorophenyl)butan-1-one DTXSID90645166.

898761-48-3 4-Chloro-1-(3,4-difluorophenyl)butan-1-one DTXSID90645166 (CAS 898761-48-3) is a high-purity analytical reference standard with the molecular formula C10H9ClF2O and a molecular weight of 218.63 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 898761-48-3 4-Chloro-1-(3,4-difluorophenyl)butan-1-one DTXSID90645166 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
