Description
As a certified reference material (CRM), 5-Fluoro-1,3-benzothiazole-2-carbaldehyde 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.
5-Fluoro-1,3-benzothiazole-2-carbaldehyde (CAS 139425-46-0), molecular formula C8H4FNOS and molecular weight 181.19 g/mol, is a CATO reference standard with documented purity and traceability.
5-Fluoro-1,3-benzothiazole-2-carbaldehyde (C8H4FNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
