Description

Compared with other compounds in its class, the molecular weight of 249.16 g/mol gives 4-((4-Chlorophenyl)thio)butanoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-((4-Chlorophenyl)thio)butanoyl chloride (CAS 89988-12-5) is a high-purity analytical reference standard with the molecular formula C10H10Cl2OS and a molecular weight of 249.16 g/mol.

The molecular framework of 4-((4-Chlorophenyl)thio)butanoyl chloride (C10H10Cl2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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 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.

As a certified reference material (CRM), 4-((4-Chlorophenyl)thio)butanoyl chloride 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.
