Chemical Structure
Description
As a certified reference material (CRM), 2,2,3,3,4,4,4-Heptafluorobutyl butyrate 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 2,2,3,3,4,4,4-Heptafluorobutyl butyrate (CAS 2926-44-5), a certified reference material (molecular formula C8H9F7O2, MW 270.14 g/mol) for analytical method development and quality control.
2,2,3,3,4,4,4-Heptafluorobutyl butyrate (C8H9F7O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
