Key value for chemical safety assessment

Additional information

No autoignition data on MMP (structural formula C4H8O2S) is available. Based on information from structural surrogates [normal octyl mercaptan (CASN 109-79-5; structural formula C4H10S) and methyl propionate (CASN 554-12-1] structural formula C4H8O2), MMP autoignition temperature may range between 225°C (446°F) to 468°C (876°F).
