(10H-Benzo[b]pyrazino[2,3-e][1,4]thiazin-8-yl)methanol (CAS 203660-01-9), molecular formula C11H9N3OS and molecular weight 231.27 g/mol, is a CATO reference standard with documented purity and traceability.
(10H-Benzo[b]pyrazino[2,3-e][1,4]thiazin-8-yl)methanol (C11H9N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (10H-Benzo[b]pyrazino[2,3-e][1,4]thiazin-8-yl)methanol 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.
