Chemical Structure
Description
2-Chloro-2,3,3-Trifluorocyclobutanecarbonyl Chloride (CAS 51504-22-4) is a high-purity analytical reference standard with the molecular formula C5H3Cl2F3O and a molecular weight of 206.98 g/mol.
The molecular framework of 2-Chloro-2,3,3-Trifluorocyclobutanecarbonyl Chloride (C5H3Cl2F3O) is characterized by a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-2,3,3-Trifluorocyclobutanecarbonyl Chloride 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.
