3,5,6-Tribromopyrazin-2-amine CAS 66490-61-7 chemical structure

Description

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

3,5,6-Tribromopyrazin-2-amine (CAS 66490-61-7) is a high-purity analytical reference standard with the molecular formula C4H2Br3N3 and a molecular weight of 331.79 g/mol.

3,5,6-Tribromopyrazin-2-amine (C4H2Br3N3) contains a nitrile group, 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.

As a certified reference material (CRM), 3,5,6-Tribromopyrazin-2-amine 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.
