Chemical Structure
Description
2-chloro-N-6,7-dihydro[1,4]dioxino[2,3-f][1,3]benzothiazol-2-ylacetamide (CAS 923744-15-4), molecular formula C11H9ClN2O3S and molecular weight 284.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-chloro-N-6,7-dihydro[1,4]dioxino[2,3-f][1,3]benzothiazol-2-ylacetamide (C11H9ClN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), 2-chloro-N-6,7-dihydro[1,4]dioxino[2,3-f][1,3]benzothiazol-2-ylacetamide 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.
