Chemical Structure
Description
The occurrence of 5-Bromo-1-ethyl-1h-1,3-benzodiazol-2-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-1-ethyl-1h-1,3-benzodiazol-2-amine (CAS 24786-56-9), molecular formula C9H10BrN3 and molecular weight 240.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-1-ethyl-1h-1,3-benzodiazol-2-amine (C9H10BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
CATO manufactures 5-Bromo-1-ethyl-1h-1,3-benzodiazol-2-amine 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.
