Chemical Structure

4-Bromo-1',3-dimethyl-5H-spiro[furan-2,3'-indolin]-2'-one CAS 870152-13-9 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 4-Bromo-1',3-dimethyl-5H-spiro[furan-2,3'-indolin]-2'-one (CAS 870152-13-9), a certified reference material (molecular formula C13H12BrNO2, MW 294.14 g/mol) for analytical method development and quality control.

4-Bromo-1',3-dimethyl-5H-spiro[furan-2,3'-indolin]-2'-one (C13H12BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

As a certified reference material (CRM), 4-Bromo-1',3-dimethyl-5H-spiro[furan-2,3'-indolin]-2'-one 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.
