Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-5-tert-butyl-1,3,4-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.
2-Bromo-5-tert-butyl-1,3,4-thiadiazole (CAS 88370-06-3), molecular formula C6H9BrN2S and molecular weight 221.12 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H9BrN2S, 2-Bromo-5-tert-butyl-1,3,4-thiadiazole contains a nitrile group, sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
