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 7-Hydrazineyl-5-isopropyl-3-phenylpyrazolo[1,5-a]pyrimidine.
CATO supplies 7-Hydrazineyl-5-isopropyl-3-phenylpyrazolo[1,5-a]pyrimidine (CAS 946259-92-3), a certified reference material (molecular formula C15H17N5, MW 267.33 g/mol) for analytical method development and quality control.
The molecular framework of 7-Hydrazineyl-5-isopropyl-3-phenylpyrazolo[1,5-a]pyrimidine (C15H17N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
