Chemical Structure

1-(4-Chlorobenzylthio)acetone CAS 40939-03-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 214.71 g/mol gives 1-(4-Chlorobenzylthio)acetone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(4-Chlorobenzylthio)acetone (CAS 40939-03-5) is a high-purity analytical reference standard with the molecular formula C10H11ClOS and a molecular weight of 214.71 g/mol.

The molecular framework of 1-(4-Chlorobenzylthio)acetone (C10H11ClOS) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1-(4-Chlorobenzylthio)acetone 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.
