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 1,3-Diethyl 2-{[(pyridin-3-yl)amino]methylidene}propanedioate.
CATO supplies 1,3-Diethyl 2-{[(pyridin-3-yl)amino]methylidene}propanedioate (CAS 14029-71-1), a certified reference material (molecular formula C13H16N2O4, MW 264.28 g/mol) for analytical method development and quality control.
1,3-Diethyl 2-{[(pyridin-3-yl)amino]methylidene}propanedioate (C13H16N2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), 1,3-Diethyl 2-{[(pyridin-3-yl)amino]methylidene}propanedioate 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.
