Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.06 g/mol gives 1,2-Dichloro-3-nitronaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,2-Dichloro-3-nitronaphthalene (CAS 6240-55-7), a certified reference material (molecular formula C10H5Cl2NO2, MW 242.06 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1,2-Dichloro-3-nitronaphthalene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 1,2-Dichloro-3-nitronaphthalene 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.
