Description of key information

A stock solution for EP-1 and EP-2 was prepaered by dissolving EP-1  anad EP-2 in demineralized water. The two compounds stability in water was determinede by measuring concentration changes of the compounds with increasing time. EP-2 was determinated with GC-NPD merhod

Key value for chemical safety assessment

Half-life for hydrolysis:
14 min

Additional information

EP-2 hydrolyze rapidly to EP-2 acid (cas no 2465 -65 -8) when dissolved in water. T½ for EP-2 is 14 minutes.
