Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 216.06 g/mol gives 2,4-dichloro-1-(2-isocyanatoethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,4-dichloro-1-(2-isocyanatoethyl)benzene (CAS 480439-41-6), a certified reference material (molecular formula C9H7Cl2NO, MW 216.06 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-dichloro-1-(2-isocyanatoethyl)benzene (C9H7Cl2NO) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2,4-dichloro-1-(2-isocyanatoethyl)benzene 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.
