Chemical Structure
Description
The molecular framework of 2-Chloro-5-(pentafluoroethyl)thiophene (C6H2ClF5S) is characterized by sulfur-containing functionality, fluorine/chlorine substitution. 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).
2-Chloro-5-(pentafluoroethyl)thiophene (CAS 1429056-29-0) is a high-purity analytical reference standard with the molecular formula C6H2ClF5S and a molecular weight of 236.59 g/mol.
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), 2-Chloro-5-(pentafluoroethyl)thiophene 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.
