Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[1-Cyano-2-(dimethylamino)vinyl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile.
CATO supplies 2-[1-Cyano-2-(dimethylamino)vinyl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 338977-21-2), a certified reference material (molecular formula C14H14N6, MW 266.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-[1-Cyano-2-(dimethylamino)vinyl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-[1-Cyano-2-(dimethylamino)vinyl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carbonitrile 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.
