4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol CAS 89221-19-2 chemical structure

Description

CATO supplies 4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol (CAS 89221-19-2), a certified reference material (molecular formula C10H11N3O, MW 189.21 g/mol) for analytical method development and quality control.

4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol (C10H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
