Chemical Structure
Description
1-[(2-chlorophenyl)methyl]-5-methyl-1h-pyrazol-3-amine (CAS 925607-55-2), molecular formula C11H12ClN3 and molecular weight 221.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-[(2-chlorophenyl)methyl]-5-methyl-1h-pyrazol-3-amine (C11H12ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 221.69 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
