Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7,8-Dihydro-6H-[1,3]dioxolo[4,5-e]isoindole.
CATO supplies 7,8-Dihydro-6H-[1,3]dioxolo[4,5-e]isoindole (CAS 1319740-28-7), a certified reference material (molecular formula C9H9NO2HCl, MW 199.63 g/mol) for analytical method development and quality control.
7,8-Dihydro-6H-[1,3]dioxolo[4,5-e]isoindole (C9H9NO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 7,8-Dihydro-6H-[1,3]dioxolo[4,5-e]isoindole 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.
