Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine hydrochloride.
CATO supplies 6,7-Dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine hydrochloride (CAS 2705222-77-9), a certified reference material (molecular formula C6H9N3OHCl, MW 175.62 g/mol) for analytical method development and quality control.
Structurally, 6,7-Dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine hydrochloride (C6H9N3OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 175.62 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 6,7-Dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine hydrochloride 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.
