Chemical Structure
Description
7-Bromo-1-methylene-2,3-dihydro-1H-indene (CAS 2102608-02-4), molecular formula C10H9Br and molecular weight 209.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Bromo-1-methylene-2,3-dihydro-1H-indene (C10H9Br) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 209.08 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Bromo-1-methylene-2,3-dihydro-1H-indene 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.
