Description
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.
Methyl 6-amino-5-cyano-2-(((3-cyano-5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)thio)methyl)-4-phenyl-4H-pyran-3-carboxylate (CAS 354556-44-8), molecular formula C27H26N4O3S and molecular weight 486.59 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C27H26N4O3S, Methyl 6-amino-5-cyano-2-(((3-cyano-5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)thio)methyl)-4-phenyl-4H-pyran-3-carboxylate contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
