Chemical Structure
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.
(S)-5-tert-Butyl 6-methyl 2-iodo-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate (CAS 2243987-12-2) is a high-purity analytical reference standard with the molecular formula C13H18IN3O4 and a molecular weight of 407.20 g/mol.
(S)-5-tert-Butyl 6-methyl 2-iodo-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate (C13H18IN3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
As a certified reference material (CRM), (S)-5-tert-Butyl 6-methyl 2-iodo-6,7-dihydro-3H-imidazo[4,5-c]pyridine-5,6(4H)-dicarboxylate 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.
