Description
Compared with other compounds in its class, the molecular weight of 154.17 g/mol gives 6-Methoxy-3,5-dimethylpyrazin-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Methoxy-3,5-dimethylpyrazin-2-ol (CAS 91678-69-2), a certified reference material (molecular formula C7H10N2O2, MW 154.17 g/mol) for analytical method development and quality control.
6-Methoxy-3,5-dimethylpyrazin-2-ol (C7H10N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
