5-Phenylpyrazine-2-carboxylic acid (CAS 13534-77-5) is a high-purity analytical reference standard with the molecular formula C11H8N2O2 and a molecular weight of 200.19 g/mol.
5-Phenylpyrazine-2-carboxylic acid (C11H8N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
