2,6-DIethyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid diethyl ester CAS 900504-04-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-DIethyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid diethyl ester.

CATO supplies 2,6-DIethyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid diethyl ester (CAS 900504-04-3), a certified reference material (molecular formula C15H23NO4, MW 281.35 g/mol) for analytical method development and quality control.

Structurally, 2,6-DIethyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid diethyl ester (C15H23NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 281.35 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 2,6-DIethyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid diethyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
