Description
As a certified reference material (CRM), 2-((4-Chlorophenyl)thio)quinoline-3-carbaldehyde 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.
2-((4-Chlorophenyl)thio)quinoline-3-carbaldehyde (CAS 749920-53-4), molecular formula C16H10ClNOS and molecular weight 299.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((4-Chlorophenyl)thio)quinoline-3-carbaldehyde (C16H10ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
