Chemical Identity & Physical Properties
| Also known as | Carbamate insecticideCarbamic acid ester pesticideN-methyl carbamate pesticideCarbaryl-type compoundsAldicarb-type compounds |
| Appearance | Typically appears as white to tan crystalline powder or granular solid with mild to no odor at room temperature. Various carbamate pesticides exist under this classification. |
| Flash Point | Varies by specific compound; typically >100C (>212F) for most carbamate solids |
| Boiling Point | Not applicable (decomposes before boiling); most carbamates decompose at 150-200C |
| Vapor Density | Not applicable (solid at room temperature) |
| Water Reactivity | Generally stable in water but slowly hydrolyzes; avoid strong acids or bases which accelerate decomposition |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
