Description
Rel-methyl (E)-2-((3S,6'R,7'S,8a'S)-6'-ethyl-2-oxo-2',3',6',7',8',8a'-hexahydro-5'H-spiro[indoline-3,1'-indolizin]-7'-yl)-3-methoxyacrylate (CAS 39032-62-7), molecular formula C22H28N2O4 and molecular weight 384.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Rel-methyl (E)-2-((3S,6'R,7'S,8a'S)-6'-ethyl-2-oxo-2',3',6',7',8',8a'-hexahydro-5'H-spiro[indoline-3,1'-indolizin]-7'-yl)-3-methoxyacrylate (C22H28N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 384.47 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Rel-methyl (E)-2-((3S,6'R,7'S,8a'S)-6'-ethyl-2-oxo-2',3',6',7',8',8a'-hexahydro-5'H-spiro[indoline-3,1'-indolizin]-7'-yl)-3-methoxyacrylate 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.
