Test Result

The test substance was observed to change colour from white to grey at approximately 260 °C, indicating likely decomposition. On continued heating to 360 °C, the sample darkened further, to dark brown in colour, with no sign of melting.

Conclusion

2MA-OK was found to decompose at approximately 260 °C, without melting.
