General description

Dimethylamine is an aliphatic secondary amine, known to be present in some foods like fish and seafoods.

Application

Dimethylamine can be used:
  • In the hydroaminoalkylation of alkenes using a transition metal.
  • To prepare dimethylformamide by reacting with carbon dioxide and hydrogen.

Packaging

500ml high pressure aluminum cylinder equipped with a stainless steel valve according to DIN 477-1.

Other Notes

For 744158-290G-EU packaging: 500 mL of aluminium cylinder equipped with stainless steel valve.

Recommended products

For 744158-290G-EU: outlet fitting: DIN 477-1 no. 1, Z742162 or Z742164 are the recommended regulators.

Transition-metal-catalyzed hydroaminoalkylations of alkenes have made great progress over the last decade and are heading to become a viable alternative to the industrial synthesis of amines through hydroformylation of alkenes and subsequent reductive amination. In the past, one major obstacle

The decline of arable species characteristic of winter cereal fields has often been attributed to different factors related to agricultural intensification but most importantly to herbicide use. Herbicide phytotoxicity is most frequently assessed using short-term endpoints, primarily aboveground biomass. However
