1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-1H-1,2,3-triazole-5-carboxylic acid CAS 1462284-58-7

Description

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.

1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-1H-1,2,3-triazole-5-carboxylic acid (CAS 1462284-58-7) is a high-purity analytical reference standard with the molecular formula C11H9N3O4 and a molecular weight of 247.21 g/mol.

1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-1H-1,2,3-triazole-5-carboxylic acid (C11H9N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
