Reactive Group Datasheet

Carbamates

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More Info...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

There are 57 chemical datasheets assigned to this reactive group.

Description

Flammability

Compounds in this group are high-boiling liquids or solids. They are generally nonflammable, but are combustible. Combustion products include noxious NOx and carbon monoxide.

Reactivity

Materials in this group are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Toxicity

Many carbamates are used as pesticides. These materials can be extremely toxic. They act by blocking the function of cholinesterase, an enzyme that is essential to the transmission of nerve impulses. Oral exposure is the principal concern. Absorption through the skin is slow, but dermal exposure must still be avoided because of the high toxicity.

Other Characteristics

Compounds in this group are derivatives of carbamic acid (NH2COOH). The urethanes are alkyl carbamates, that is, esters of carbamic acid.

Examples

Carbamic acid, ammonium carbamate, carbaryl, oxamyl, propoxur, urethane.
