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 2-Chloro-5-(trifluoromethyl)thiophene-3-carbaldehyde.
CATO supplies 2-Chloro-5-(trifluoromethyl)thiophene-3-carbaldehyde (CAS 1260667-21-7), a certified reference material (molecular formula C6H2ClF3OS, MW 214.59 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-5-(trifluoromethyl)thiophene-3-carbaldehyde (C6H2ClF3OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
CATO manufactures 2-Chloro-5-(trifluoromethyl)thiophene-3-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
