Chemical Structure
Description
4-(4-Methoxy-2H-1,2,3-triazol-2-yl)benzaldehyde (CAS 65145-91-7), molecular formula C10H9N3O2 and molecular weight 203.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Methoxy-2H-1,2,3-triazol-2-yl)benzaldehyde (C10H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 4-(4-Methoxy-2H-1,2,3-triazol-2-yl)benzaldehyde 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.
