Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl ((1H-pyrazol-3-yl)methyl)carbamate.
Benzyl ((1H-pyrazol-3-yl)methyl)carbamate (CAS 1291937-65-9) is a high-purity analytical reference standard with the molecular formula C12H13N3O2 and a molecular weight of 231.25 g/mol.
Based on its molecular formula C12H13N3O2, Benzyl ((1H-pyrazol-3-yl)methyl)carbamate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 231.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
