Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Chloro-3-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)amino)naphthalene-1,4-dione (CAS 298215-14-2), a certified reference material (molecular formula C18H12ClNO4, MW 341.75 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-3-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)amino)naphthalene-1,4-dione (C18H12ClNO4) is characterized by a flavonoid core, 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.
As a certified reference material (CRM), 2-Chloro-3-((2,3-dihydrobenzo[b][1,4]dioxin-6-yl)amino)naphthalene-1,4-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
