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.

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
