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 7-Chloro-2,3-dihydro-[1,4]dioxino-[2,3-b]pyridine-8-carbaldehyde oxime (CAS 1346451-49-7), a certified reference material (molecular formula C8H7ClN2O3, MW 214.61 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-2,3-dihydro-[1,4]dioxino-[2,3-b]pyridine-8-carbaldehyde oxime (C8H7ClN2O3) 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.
CATO manufactures 7-Chloro-2,3-dihydro-[1,4]dioxino-[2,3-b]pyridine-8-carbaldehyde oxime 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.
