FAQ
Frequently Asked Questions
It depends on the specific compound. Some carbamates are safe pharmaceuticals (e.g., meprobamate), while others are potent insecticides toxic to humans and pests alike. Always refer to the specific compound's safety data.
A carbamate contains nitrogen (NH2 or NHR group) bonded to the carbonyl carbon (C=O). A carbonate has two oxygen atoms single-bonded to the carbon (O-C-O), with no nitrogen directly attached to the carbonyl carbon.
Yes, in technical jargon. 'To carbamate' means to introduce a carbamate group into a molecule, typically by reacting an amine with carbon dioxide or a chloroformate.
Ethyl carbamate is historically and commonly called 'urethane'. However, in modern precise terminology, 'urethane' more often refers to polymers (polyurethanes), while 'carbamate' is the general term for the chemical class. They are often used interchangeably for the simple ester.
A salt or ester of carbamic acid, containing the NH2COO- group.
Carbamate is usually technical/scientific in register.
Carbamate: in British English it is pronounced /ˈkɑː.bə.meɪt/, and in American English it is pronounced /ˈkɑːr.bə.meɪt/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: CARBOn + AMATE (as in 'amate' from ammonia/amine). It's a compound where a carbon atom is bonded to both an amine group (NH2) and an oxygen (from an acid).
Conceptual Metaphor
A carbamate is often conceptualized as a 'BUILDING BLOCK' or 'KEY' in chemical synthesis and drug design, or as a 'SWORD' with dual nature (useful drug vs. toxic insecticide).
