Chemical Structure
Description
Ethyl (4aS,8aR)-2-thioxooctahydro-1,6-naphthyridine-6(2H)-carboxylate (CAS 1644283-97-5) is a high-purity analytical reference standard with the molecular formula C11H18N2O2S and a molecular weight of 242.34 g/mol.
Ethyl (4aS,8aR)-2-thioxooctahydro-1,6-naphthyridine-6(2H)-carboxylate (C11H18N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ethyl (4aS,8aR)-2-thioxooctahydro-1,6-naphthyridine-6(2H)-carboxylate 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.
