Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Methyl phosphonic acid (MPA) is an organic phosphorous substance with a very low volatility. The purified chemical is solid at room temperature forming white crystals. MPA has a flash point >200 °C. MPA does not contain chemical groups associated with explosive properties.

Justification for classification or non-classification

MPA does not contain chemical groups associated with explosive properties, therefore classification of the substance for explosive properties is not considered.
