Chemical Structure
Description
The occurrence of Diethyl 2-(3,4-Dichlorophenyl)malonate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Diethyl 2-(3,4-Dichlorophenyl)malonate (CAS 28751-26-0), a certified reference material (molecular formula C13H14Cl2O4, MW 305.15 g/mol) for analytical method development and quality control.
Structurally, Diethyl 2-(3,4-Dichlorophenyl)malonate (C13H14Cl2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 305.15 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(3,4-Dichlorophenyl)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.
