Chemical Structure
Description
1,2,4,5,6,7,8,8-Octachloro-3a,4,7,7a-tetrahydro-4,7-methano-1H-indene (CAS 23285-69-0) is a high-purity analytical reference standard with the molecular formula C10H4Cl8 and a molecular weight of 407.76 g/mol.
Owing to chlorine substitution, an aromatic ring system, 1,2,4,5,6,7,8,8-Octachloro-3a,4,7,7a-tetrahydro-4,7-methano-1H-indene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.76 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
