Chemical Structure
Description
4-(2-bromoethyl)-1H-pyrazole hydrobromide (CAS 1803601-03-7), molecular formula C5H7BrN2HBr and molecular weight 255.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-bromoethyl)-1H-pyrazole hydrobromide (C5H7BrN2HBr) is characterized by a nitrile group, bromine 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.
CATO manufactures 4-(2-bromoethyl)-1H-pyrazole hydrobromide 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.
