Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Cyclopropyl-2-((3,4-dichlorophenyl)thio)ethan-1-one.
1-Cyclopropyl-2-((3,4-dichlorophenyl)thio)ethan-1-one (CAS 1478844-83-5), molecular formula C11H10Cl2OS and molecular weight 261.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Cyclopropyl-2-((3,4-dichlorophenyl)thio)ethan-1-one (C11H10Cl2OS) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Cyclopropyl-2-((3,4-dichlorophenyl)thio)ethan-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.
