Chemical Structure

5-Bromo-1-methyl-1H-1,2,4-triazole CAS 16681-72-4 chemical structure

Description

As a certified reference material (CRM), 5-Bromo-1-methyl-1H-1,2,4-triazole 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-Bromo-1-methyl-1H-1,2,4-triazole (CAS 16681-72-4) is a high-purity analytical reference standard with the molecular formula C3H8BrN3 and a molecular weight of 166.02 g/mol.

5-Bromo-1-methyl-1H-1,2,4-triazole (C3H8BrN3) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
