NTP Toxicology and Carcinogenesis Studies of 3-Chloro-2-methylpropene (Technical grade containing 5% dimethylvinyl chloride) (CAS No. 563-47-3) in F344/N Rats and B6C3F1 Mice (Gavage Studies).

National Toxicology Program technical report series, 300, 1-196 (1986-06-01)

Toxicology and carcinogenesis studies of technical-grade 3-chloro-2-methylpropene (containing 5% dimethylvinyl chloride), a widely used insecticide and a chemical intermediate, were performed on F344/N rats and B6C3F1 mice. In the 13-week studies, 50%-100% mortality occurred in groups of male and female

Controlled release of 1-methylcyclopropene from its functionalised electrospun fibres under constant and linearly ramped humidity.

The methodology to electrospin polystyrene (PS) fibres functionalised with the inclusion complex between 1-methylcyclopropene (1-MCP) and α-cyclodextrin (α-CD) has been developed successfully. Due to limited availability, α-CD crystals instead of 1-MCP/α-CD complex were suspended in the electrospinning (ES) solutions to
