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 3-(Cyclopentylmethyl)-1-methyl-1h-pyrazol-5-amine.
3-(Cyclopentylmethyl)-1-methyl-1h-pyrazol-5-amine (CAS 97820-73-0), molecular formula C10H17N3 and molecular weight 179.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(Cyclopentylmethyl)-1-methyl-1h-pyrazol-5-amine (C10H17N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
