Description
CATO manufactures 4-Iodo-3-(4-nitrophenyl)-1H-pyrazole 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.
4-Iodo-3-(4-nitrophenyl)-1H-pyrazole (CAS 1339261-01-6), molecular formula C9H6IN3O2 and molecular weight 315.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Iodo-3-(4-nitrophenyl)-1H-pyrazole (C9H6IN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
