(1aR,2R,2aS,3S,6R,6aR,7S,7aS)-rel-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-one 12-Keto Dieldrin 52745-99-0 WL 42170 (CAS 52745-99-0), molecular formula C12H6Cl6O2 and molecular weight 394.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (1aR,2R,2aS,3S,6R,6aR,7S,7aS)-rel-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-one 12-Keto Dieldrin 52745-99-0 WL 42170 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
