Description
3-[(3S)-Pyrrolidin-3-yl]-3,4-dihydro-1H-2lambda(6),1,3-benzothiadiazine-2,2-dione hydrochloride (CAS 1389309-97-0), molecular formula C11H15N3O2SHCl and molecular weight 289.78 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(3S)-Pyrrolidin-3-yl]-3,4-dihydro-1H-2lambda(6),1,3-benzothiadiazine-2,2-dione hydrochloride (C11H15N3O2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-[(3S)-Pyrrolidin-3-yl]-3,4-dihydro-1H-2lambda(6),1,3-benzothiadiazine-2,2-dione hydrochloride 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.
