Chemical Structure
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.
2-((1H-Imidazol-2-yl)methylene)-1-(tert-butyl)hydrazinecarboxylic acid (CAS 348628-29-5) is a high-purity analytical reference standard with the molecular formula C9H14N4O2 and a molecular weight of 210.23 g/mol.
Structurally, 2-((1H-Imidazol-2-yl)methylene)-1-(tert-butyl)hydrazinecarboxylic acid (C9H14N4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 210.23 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
