Description of key information

The partition Coefficient n-octanol/water of 2-hydroxynaphthalene-1-carbaldehyde [(2-hydroxy-1-naphthyl) methylene] hydrazone(CAS No. 2387-03-3) was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 117 for testing of Chemicals. The reference substances were chosen according to structural similarity with the test substance. The reference substances were4 acetyl pyridine,Benzene,Toluene,Ethylbenzene,Naphthalene, Biphenyl, n butyl benzene, DDThaving Pow value ranging from 0.5 to 6.5. TheLog Powvalue was found tobe6.269 ± 0.007at 25°C.
