Test material

1
Chemical structure
Reference substance name:
Oligomerisation and alkylation reaction products of 2-phenylpropene and phenol
EC Number:
700-960-7
Cas Number:
68512-30-1
Molecular formula:
not applicable
IUPAC Name:
Oligomerisation and alkylation reaction products of 2-phenylpropene and phenol
Test material form:
liquid: viscous
Details on test material:
- Manufacturers identification: Novares LA 300
- Substance type: organic
- Test material is 'Oligomerisation and alkylation reaction products of 2-phenylpropene and phenol' (OAPP), EC list number 700-960-7 (assigned manually to validated substances from inquiries by ECHA). Originally the substance phenol, methylstyrenated, CAS No. 68512-30-1, EC No. 270-966-8 was submitted for registration. Subsequent to substance validation, the identity of the substance was changed by ECHA.
