Chemical Structure
Description
As a certified reference material (CRM), 3-Benzyl-5-chloro-1,2,4-thiadiazole 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.
CATO supplies 3-Benzyl-5-chloro-1,2,4-thiadiazole (CAS 99067-57-9), a certified reference material (molecular formula C9H7ClN2S, MW 210.68 g/mol) for analytical method development and quality control.
3-Benzyl-5-chloro-1,2,4-thiadiazole (C9H7ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
