Chemical Structure
Description
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.
3-Amino-2-iminohexahydrothieno[3,4-d]thiazole 5,5-dioxide hydrobromide (CAS 255871-99-9) is a high-purity analytical reference standard with the molecular formula C5H9N3O2S2HBr and a molecular weight of 288.18 g/mol.
Structurally, 3-Amino-2-iminohexahydrothieno[3,4-d]thiazole 5,5-dioxide hydrobromide (C5H9N3O2S2HBr) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 288.18 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.
