| 21. | There are several subgroups within the carbamates.
|
| 22. | These compounds are nonpersistent sodium channel modulators and are less toxic than organophosphates and carbamates.
|
| 23. | Methyl carbamate is used primarily in the textile and polymer industries as a reactive intermediate.
|
| 24. | Methyl carbamate also is used in the manufacture of pharmaceuticals, insecticides, and urethane.
|
| 25. | The deprotonated anion ( or conjugate base ) of this functional group is a carbamate.
|
| 26. | Because the urea conversion is incomplete, the product must be separated from unchanged ammonium carbamate.
|
| 27. | Organophosphate and carbamates largely replaced organochlorines.
|
| 28. | Carbamate pesticides affect the nervous system by disrupting an enzyme that regulates acetylcholine, a neurotransmitter.
|
| 29. | Ethyl carbamate is frequently used as an anaesthetic in cortex to the same extent as isoflurane.
|
| 30. | It poses lower risks to mammals, including humans, when compared to organophosphates and carbamates.
