Chemical Structure
Description
CATO supplies 5,5-Dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-3-amine (CAS 2170752-31-3), a certified reference material (molecular formula C8H13N3O, MW 167.21 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5,5-Dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.21 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.
As a certified reference material (CRM), 5,5-Dimethyl-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-3-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.
