158076-69-8 1TO9EBC07Z 2,2',3',4,4',5,5'-Heptachloro-3-biphenylol UNII-1TO9EBC07Z (1,1'-Biphenyl)-3-ol, 2,2',3',4,4',5,5'-heptachloro- 2,2',3,4,4',5,5'-Heptachloro-3'-hydroxy-1,1'-biphenyl 3'-Hydroxy-2,2',3,4,4',5,5'-heptachlorobiphenyl 3-Hydroxy-2,2',3',4,4',5,5'-heptachlorobiphenyl 3'-Hydroxy-PCB 180 (CAS 158076-69-8), molecular formula C12H3Cl7O and molecular weight 411.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 158076-69-8 1TO9EBC07Z 2,2',3',4,4',5,5'-Heptachloro-3-biphenylol UNII-1TO9EBC07Z (1,1'-Biphenyl)-3-ol, 2,2',3',4,4',5,5'-heptachloro- 2,2',3,4,4',5,5'-Heptachloro-3'-hydroxy-1,1'-biphenyl 3'-Hydroxy-2,2',3,4,4',5,5'-heptachlorobiphenyl 3-Hydroxy-2,2',3',4,4',5,5'-heptachlorobiphenyl 3'-Hydroxy-PCB 180 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 411.32 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.
