Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.67 g/mol gives 1-isopropyl-5-methyl-pyrazole-3-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-isopropyl-5-methyl-pyrazole-3-carbonyl chloride (CAS 854699-35-7), molecular formula C8H15ClN2O and molecular weight 190.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-isopropyl-5-methyl-pyrazole-3-carbonyl chloride (C8H15ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.
