Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Heptafluorobutyryl-5(3)-(heptafluoropropyl)-3(5)-(trifluoromethyl)pyrazole (CAS 959580-65-5), a certified reference material (molecular formula C11HF17N2O, MW 500.11 g/mol) for analytical method development and quality control.
Structurally, 1-Heptafluorobutyryl-5(3)-(heptafluoropropyl)-3(5)-(trifluoromethyl)pyrazole (C11HF17N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 500.11 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 1-Heptafluorobutyryl-5(3)-(heptafluoropropyl)-3(5)-(trifluoromethyl)pyrazole 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.
