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-(2,4-Dichlorobenzyl)-2-(3-nitropyridin-2-yl)malononitrile.
2-(2,4-Dichlorobenzyl)-2-(3-nitropyridin-2-yl)malononitrile (CAS 439095-07-5) is a high-purity analytical reference standard with the molecular formula C15H8Cl2N4O2 and a molecular weight of 347.16 g/mol.
The molecular framework of 2-(2,4-Dichlorobenzyl)-2-(3-nitropyridin-2-yl)malononitrile (C15H8Cl2N4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(2,4-Dichlorobenzyl)-2-(3-nitropyridin-2-yl)malononitrile 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.
