(R)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine CAS 2416268-40-9

Description

(R)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine (CAS 2416268-40-9) is a high-purity analytical reference standard with the molecular formula C6H9N3O and a molecular weight of 139.16 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, (R)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.16 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (R)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazin-6-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.
