Chemical Structure
Description
5-Amino-N-cyclohexyl-1-ethyl-N-methyl-1H-pyrazole-3-carboxamide (CAS 1856071-05-0), molecular formula C13H22N4O and molecular weight 250.34 g/mol, is a CATO reference standard with documented purity and traceability.
5-Amino-N-cyclohexyl-1-ethyl-N-methyl-1H-pyrazole-3-carboxamide (C13H22N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
