Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-(Piperazin-1-ylsulfonyl)-2H-benzo[b][1,4]oxazin-3(4H)-one hydrochloride (CAS 1269151-32-7), a certified reference material (molecular formula C12H15N3O4SHCl, MW 333.79 g/mol) for analytical method development and quality control.
Structurally, 6-(Piperazin-1-ylsulfonyl)-2H-benzo[b][1,4]oxazin-3(4H)-one hydrochloride (C12H15N3O4SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 333.79 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
