Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 6-Chloro-9-(3,5-dihydro-2H-benzo[e][1,4]dioxepin-3-yl)-9H-purine (CAS 918304-34-4), a certified reference material (molecular formula C14H11ClN4O2, MW 302.72 g/mol) for analytical method development and quality control.
6-Chloro-9-(3,5-dihydro-2H-benzo[e][1,4]dioxepin-3-yl)-9H-purine (C14H11ClN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 6-Chloro-9-(3,5-dihydro-2H-benzo[e][1,4]dioxepin-3-yl)-9H-purine 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.
