Chemical Structure
Description
4-bromo-2,3-dihydro-1H-inden-2-one (CAS 846032-36-8) is a high-purity analytical reference standard with the molecular formula C9H13BrO and a molecular weight of 217.10 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, 4-bromo-2,3-dihydro-1H-inden-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.10 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), 4-bromo-2,3-dihydro-1H-inden-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.
