Chemical Structure

9-epi-Cinchonidine CAS 550-54-9 chemical structure

Description

As a certified reference material (CRM), 9-epi-Cinchonidine 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.

9-epi-Cinchonidine (CAS 550-54-9) is a high-purity analytical reference standard with the molecular formula C19H22N2O and a molecular weight of 294.39 g/mol.

9-epi-Cinchonidine (C19H22N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
