Chemical Structure
Description
As a certified reference material (CRM), 5'-Bromo-1'-ethenyl-1',2'-dihydrospiro[cyclopropane-1,3'-indole]-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.
5'-Bromo-1'-ethenyl-1',2'-dihydrospiro[cyclopropane-1,3'-indole]-2'-one (CAS 1788054-77-2), molecular formula C12H10BrNO and molecular weight 264.12 g/mol, is a CATO reference standard with documented purity and traceability.
5'-Bromo-1'-ethenyl-1',2'-dihydrospiro[cyclopropane-1,3'-indole]-2'-one (C12H10BrNO) 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; 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.
