Chemical Structure
Description
As a certified reference material (CRM), 3-[(1,1-Dioxido-1,2-benzisothiazol-3-yl)amino]-1-propanol 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.
3-[(1,1-Dioxido-1,2-benzisothiazol-3-yl)amino]-1-propanol (CAS 68287-29-6), molecular formula C10H12N2O3S and molecular weight 240.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-[(1,1-Dioxido-1,2-benzisothiazol-3-yl)amino]-1-propanol (C10H12N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
