Toxicity index formula
WebIn toxicology, the median lethal dose, LD50 (abbreviation for " lethal dose, 50%"), LC50 (lethal concentration, 50%) or LCt50 is a toxic unit that measures the lethal dose of a toxin, radiation, or pathogen. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration. WebDimethylacetamide ( DMAc or DMA) is the organic compound with the formula CH 3 C (O)N (CH 3) 2. This colorless, water-miscible, high-boiling liquid is commonly used as a polar solvent in organic synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons .
