Description
As a certified reference material (CRM), 3-Isopentyl-2,5-dimethylpyrazine 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.
CATO supplies 3-Isopentyl-2,5-dimethylpyrazine (CAS 18433-98-2), a certified reference material (molecular formula C11H18N2, MW 178.27 g/mol) for analytical method development and quality control.
3-Isopentyl-2,5-dimethylpyrazine (C11H18N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
