Description
CATO manufactures 7-Bromo-1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 7-Bromo-1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazine (CAS 1781900-31-9), a certified reference material (molecular formula C10H10BrN3, MW 252.11 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 7-Bromo-1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
