55804-67-6 2773GTW04S Coumarin 521 10-Acetyl-2,3,6,7-tetrahydro-1H,5H,11H-(1)benzopyrano(6,7,8-ij)quinolizin-11-one 1H,5H,11H-(1)Benzopyrano(6,7,8-ij)quinolizin-11-one, 10-acetyl-2,3,6,7-tetrahydro- EINECS 259-826-7 NSC 369287 Coumarin 334 UNII-2773GTW04S (CAS 55804-67-6), molecular formula C17H23NO3 and molecular weight 289.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 55804-67-6 2773GTW04S Coumarin 521 10-Acetyl-2,3,6,7-tetrahydro-1H,5H,11H-(1)benzopyrano(6,7,8-ij)quinolizin-11-one 1H,5H,11H-(1)Benzopyrano(6,7,8-ij)quinolizin-11-one, 10-acetyl-2,3,6,7-tetrahydro- EINECS 259-826-7 NSC 369287 Coumarin 334 UNII-2773GTW04S is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
