Test material

Constituent 1
Chemical structure
Reference substance name:
Anthranilamide
EC Number:
201-851-2
EC Name:
Anthranilamide
Cas Number:
88-68-6
Molecular formula:
C7H8N2O
IUPAC Name:
2-aminobenzamide
Details on test material:
- Name of test material (as cited in study report): Anthranilamide
- Physical state: solid /beige
- Analytical purity: 97.3 %
- Lot/batch No.: 0005190619
- Stability under test conditions: stable
