CATO supplies 2-Isobutyl-3,5,6-trimethylpyrazine (CAS 46187-37-5), a certified reference material (molecular formula C11H18N2, MW 178.27 g/mol) for analytical method development and quality control.
Structurally, 2-Isobutyl-3,5,6-trimethylpyrazine (C11H18N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 178.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-Isobutyl-3,5,6-trimethylpyrazine 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.
