4,8-Dihydrobis([1,2,5]oxadiazolo)[3,4-b:3',4'-e]pyrazine CAS 132029-07-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,8-Dihydrobis([1,2,5]oxadiazolo)[3,4-b:3',4'-e]pyrazine.

4,8-Dihydrobis([1,2,5]oxadiazolo)[3,4-b:3',4'-e]pyrazine (CAS 132029-07-3), molecular formula C4H2N6O2 and molecular weight 166.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4,8-Dihydrobis([1,2,5]oxadiazolo)[3,4-b:3',4'-e]pyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.10 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
