Chemical Structure
Description
The occurrence of (2Z)-3-(5-Amino-1H-1,2,4-triazol-3-yl)acrylic acid nitrate is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2Z)-3-(5-Amino-1H-1,2,4-triazol-3-yl)acrylic acid nitrate (CAS 1350301-56-2), molecular formula C5H6N4O2HNO3 and molecular weight 217.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, (2Z)-3-(5-Amino-1H-1,2,4-triazol-3-yl)acrylic acid nitrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
