Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 5-Methyl-3-(1,2,2,2-tetrafluoro-1-(perfluoropropoxy)ethyl)-1H-pyrazole (CAS 229957-00-0), a certified reference material (molecular formula C9H5F11N2O, MW 366.13 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-3-(1,2,2,2-tetrafluoro-1-(perfluoropropoxy)ethyl)-1H-pyrazole (C9H5F11N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
