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 Methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate.
CATO supplies Methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate (CAS 203792-50-1), a certified reference material (molecular formula C7H9N3O3, MW 183.16 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H9N3O3, Methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate 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 183.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
