Chemical Structure
Description
1-(4-Chloro-3-fluorophenyl)-1H-1,2,3-triazole-4-carbaldehyde (C9H5ClFN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(4-Chloro-3-fluorophenyl)-1H-1,2,3-triazole-4-carbaldehyde (CAS 1492834-85-1), molecular formula C9H5ClFN3O and molecular weight 225.61 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
