CATO supplies (8|A)-9,10-Didehydro-2,3-dihydro-3-hydroxy-N,6-dimethyl-2-oxo-N-propylergoline-8-carboxamide 2-Oxo-3-hydroxy LAMPA 2-Oxo-3-hydroxy-N-methyl-N-propyl D-Lysergamide 2-Oxo-3-hydroxylysergic Acid Methyl Propyl Amide 249921-57-1 (CAS 249921-57-1), a certified reference material (molecular formula C20H25N3O3, MW 355.43 g/mol) for analytical method development and quality control.

(8|A)-9,10-Didehydro-2,3-dihydro-3-hydroxy-N,6-dimethyl-2-oxo-N-propylergoline-8-carboxamide 2-Oxo-3-hydroxy LAMPA 2-Oxo-3-hydroxy-N-methyl-N-propyl D-Lysergamide 2-Oxo-3-hydroxylysergic Acid Methyl Propyl Amide 249921-57-1 (C20H25N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
