Description
CATO supplies 3-Cyclopropyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-4-carboxylic acid (CAS 18904-34-2), a certified reference material (molecular formula C7H4ClF3S, MW 212.62 g/mol) for analytical method development and quality control.
3-Cyclopropyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-4-carboxylic acid (C7H4ClF3S) contains sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Cyclopropyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-4-carboxylic acid 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.
