Description
1-Mesityl-5-((9-methyl-11-oxo-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-10-yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-trione (CAS 840457-43-4), molecular formula C30H29N3O5 and molecular weight 511.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Mesityl-5-((9-methyl-11-oxo-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-10-yl)methylene)pyrimidine-2,4,6(1H,3H,5H)-trione (C30H29N3O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 511.57 g/mol, it falls into the moderately-high-molecular-weight range. 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.
