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-Tert-butyl-1-(pyrimidin-2-yl)-1h-pyrazol-5-amine.
3-Tert-butyl-1-(pyrimidin-2-yl)-1h-pyrazol-5-amine (CAS 862368-63-6), molecular formula C11H15N5 and molecular weight 217.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Tert-butyl-1-(pyrimidin-2-yl)-1h-pyrazol-5-amine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 217.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
