Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 26946-01-0 3,4,5,6,9,9-Hexachloro-1a,2,2a,3,6,6a,7,7a-octahydro-2,7:3,6-dimethanonaphth[2,3-b]oxiren-8-ol 9-(syn-Epoxy)hydroxy-1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-1,4-endo-5,8-exo-dimethanonaphthalene 9-Hydroxy-HEOD 9-syn-Hydroxy HEOD WL 40231 syn-12-Hydroxy Dieldrin is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
