Typical Characteristics

MMT is extremely photosensitive and decomposes rapidly when exposed to light. The half life of MMT vapor in air is less than one minute when exposed to light. Photolytic action converts the organic compound to a mixture of non-hazardous manganese oxides, carbonates and organics derived from methylcyclopentadiene.
