Chemical Structure
Description
The occurrence of 7-methyl-1H-pyrazolo[4,3-d]pyrimidin-5-amine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-methyl-1H-pyrazolo[4,3-d]pyrimidin-5-amine (CAS 63019-49-8) is a high-purity analytical reference standard with the molecular formula C6H7N5 and a molecular weight of 149.15 g/mol.
The molecular framework of 7-methyl-1H-pyrazolo[4,3-d]pyrimidin-5-amine (C6H7N5) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-methyl-1H-pyrazolo[4,3-d]pyrimidin-5-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
