Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 346.90 g/mol gives Diethyl 2-(pyridin-2-ylmethyl)malonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl 2-(pyridin-2-ylmethyl)malonate (CAS 3243-01-4), molecular formula C14H19ClN2O2S2 and molecular weight 346.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl 2-(pyridin-2-ylmethyl)malonate (C14H19ClN2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures Diethyl 2-(pyridin-2-ylmethyl)malonate 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.
