Applicant's summary and conclusion

Executive summary:

The rate of indirect photolysis in Air via Hydroxyl radicals is estimated by calculation = 6.9851 E-12 cm3/molecule*sec.

Half life 1.531 days, calculated 12 h a day.

Moreover 2,5-Dichlorophenol contains chromophores that absorb at wavelengths >290 nm and therefore may be susceptible to direct photolysis by sunlight. (HSDB)
