Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methylpyrazolo[1,5-a]pyrimidin-7-amine.
CATO supplies 5-Methylpyrazolo[1,5-a]pyrimidin-7-amine (CAS 2369-88-2), a certified reference material (molecular formula C7H8N4, MW 148.17 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methylpyrazolo[1,5-a]pyrimidin-7-amine (C7H8N4) is characterized by a nitrile group, an aromatic ring system. 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. 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.
