Description of key information

The atmospheric oxidation half life of  phthalylsulfathiazole was estimated using level III multimedia model it indicates that phthalylsulfathiazole  is rapidly phototransformed in air.

Key value for chemical safety assessment

Half-life in air:
0.15 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1

Additional information

The atmospheric oxidation half life of phthalylsulfathiazole was estimated using level III multimedia model it indicates that phthalylsulfathiazole is not persistent in air medium as the half life period of phthalylsulfathiazole in air is only 0.15 days. From this it is concluded that phthalylsulfathiazole is rapidly phototransformed in air.
