Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.04 g/mol gives 2,3-D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3-D (CAS 2976-74-1), a certified reference material (molecular formula C8H6Cl2O3, MW 221.04 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H6Cl2O3, 2,3-D contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2,3-D 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.
