Ethyl 3-methoxypyrido[1,2-a]indole-10-carboxylate (CAS 22991-18-0) is a high-purity analytical reference standard with the molecular formula C16H15NO3 and a molecular weight of 269.30 g/mol.
Ethyl 3-methoxypyrido[1,2-a]indole-10-carboxylate (C16H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
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.
As a certified reference material (CRM), Ethyl 3-methoxypyrido[1,2-a]indole-10-carboxylate 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.
