Chemical Structure
Description
As a certified reference material (CRM), 3-Bromopyrazolo[1,5-a]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.
CATO supplies 3-Bromopyrazolo[1,5-a]pyrimidin-5-amine (CAS 2413085-89-7), a certified reference material (molecular formula C6H5BrN4, MW 213.03 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 3-Bromopyrazolo[1,5-a]pyrimidin-5-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
