Description
As a certified reference material (CRM), 3-((2,4-Dichlorobenzyl)thio)thiophene-2-carboxylic acid 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.
CATO supplies 3-((2,4-Dichlorobenzyl)thio)thiophene-2-carboxylic acid (CAS 251097-45-7), a certified reference material (molecular formula C12H8Cl2O2S2, MW 319.23 g/mol) for analytical method development and quality control.
The molecular framework of 3-((2,4-Dichlorobenzyl)thio)thiophene-2-carboxylic acid (C12H8Cl2O2S2) is characterized by a sulfone group, a carboxylic acid group, 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 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.
