Chemical Structure
Description
Diethyl 2,6-dimethyl-4-(quinolin-4-yl)pyridine-3,5-dicarboxylate (CAS 5402-90-4) is a high-purity analytical reference standard with the molecular formula C19H31NO2HCl and a molecular weight of 341.92 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Diethyl 2,6-dimethyl-4-(quinolin-4-yl)pyridine-3,5-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Diethyl 2,6-dimethyl-4-(quinolin-4-yl)pyridine-3,5-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.
