6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-sulfonamide CAS 1803609-80-4

Description

The occurrence of 6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-sulfonamide (CAS 1803609-80-4), molecular formula C6H13N3O3S and molecular weight 207.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H13N3O3S, 6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine-3-sulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 207.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
