Chemical Structure
Description
The occurrence of 2-Chloronaphthalene-1,3-dicarbaldehyde 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.
2-Chloronaphthalene-1,3-dicarbaldehyde (CAS 132554-61-1) is a high-purity analytical reference standard with the molecular formula C12H7ClO2 and a molecular weight of 218.64 g/mol.
The molecular framework of 2-Chloronaphthalene-1,3-dicarbaldehyde (C12H7ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).
