After evaporation or exposure to the air, the product will be slowly degraded by photochemical processes with OH-radicals.
Based on the
calculation according to SRC AOP v1.92,d-valerolactone is indirectly
photodegraded by reaction with hydroxyl radicals in the atmosphere with
a half-life (t1/2) of about 77 hours taking into account a 24-h day and
a mean OH radical concentration of 5.0E+05 molecules per cm³ (BASF 2011).
