2H-1,2,3-Triazole-4-carbaldehyde CAS 4343-71-9

Description

Compared with other compounds in its class, the molecular weight of 97.08 g/mol gives 2H-1,2,3-Triazole-4-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2H-1,2,3-Triazole-4-carbaldehyde (CAS 4343-71-9), a certified reference material (molecular formula C3H3N3O, MW 97.08 g/mol) for analytical method development and quality control.

Structurally, 2H-1,2,3-Triazole-4-carbaldehyde (C3H3N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 97.08 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
