Key value for chemical safety assessment

Additional information

Since the registered UVCB substance is not readily biodegradable, EPISUITE (HENRYWIN v3.20) was used to predict Henry's Law constant for an environmentally relevant constituent. The result for EC 273 -279 -1 was calculated as 23.0 Pa.m3/moL indicating that the substance is very likely to parition to air.
