5-Bromo-1-(1,2,4-oxadiazol-3-ylmethyl)-2,3-dihydro-1h-indole-2,3-dione CAS 1042633-64-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-1-(1,2,4-oxadiazol-3-ylmethyl)-2,3-dihydro-1h-indole-2,3-dione.

5-Bromo-1-(1,2,4-oxadiazol-3-ylmethyl)-2,3-dihydro-1h-indole-2,3-dione (CAS 1042633-64-6) is a high-purity analytical reference standard with the molecular formula C11H6BrN3O3 and a molecular weight of 308.09 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 5-Bromo-1-(1,2,4-oxadiazol-3-ylmethyl)-2,3-dihydro-1h-indole-2,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 5-Bromo-1-(1,2,4-oxadiazol-3-ylmethyl)-2,3-dihydro-1h-indole-2,3-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.
