4-((2,5-Dichlorophenyl)thio)pentan-2-one CAS 1341522-46-0

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-((2,5-Dichlorophenyl)thio)pentan-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.18 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).

4-((2,5-Dichlorophenyl)thio)pentan-2-one (CAS 1341522-46-0), molecular formula C11H12Cl2OS and molecular weight 263.18 g/mol, is a CATO reference standard with documented purity and traceability.

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.
