Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dimethoxy-2,1,3-benzothiadiazole.
5,6-Dimethoxy-2,1,3-benzothiadiazole (CAS 1254353-35-9) is a high-purity analytical reference standard with the molecular formula C8H8N2O2S and a molecular weight of 196.23 g/mol.
5,6-Dimethoxy-2,1,3-benzothiadiazole (C8H8N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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), 5,6-Dimethoxy-2,1,3-benzothiadiazole 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.
