Chemical Structure
Description
8-Acetyl-4-methyl-1,2,3,4-tetrahydroquinoxaline-5-carbaldehyde (CAS 89334-26-9), molecular formula C12H14N2O2 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.
8-Acetyl-4-methyl-1,2,3,4-tetrahydroquinoxaline-5-carbaldehyde (C12H14N2O2) 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 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.
CATO manufactures 8-Acetyl-4-methyl-1,2,3,4-tetrahydroquinoxaline-5-carbaldehyde 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.
