Chemical Structure
Description
The molecular framework of (5-Amino-1-methyl-1H-pyrazol-3-yl)(1H-imidazol-1-yl)methanone (C8H9N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(5-Amino-1-methyl-1H-pyrazol-3-yl)(1H-imidazol-1-yl)methanone (CAS 1856102-42-5) is a high-purity analytical reference standard with the molecular formula C8H9N5O and a molecular weight of 191.19 g/mol.
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.
