(E)-6-(2,6-dimethylmorpholino)nicotinaldehyde O-(2,6-dichlorobenzyl) oxime (CAS 866040-98-4), molecular formula C19H21Cl2N3O2 and molecular weight 394.29 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-6-(2,6-dimethylmorpholino)nicotinaldehyde O-(2,6-dichlorobenzyl) oxime (C19H21Cl2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (E)-6-(2,6-dimethylmorpholino)nicotinaldehyde O-(2,6-dichlorobenzyl) oxime 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.
