Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. [ 7 ] It can be thought of chemically as the double acyl chloride analog of carbonic acid , or structurally as formaldehyde with the hydrogen atoms replaced by chlorine ...
Phosphine is an attractive fumigant because it is lethal to insects and rodents, but degrades to phosphoric acid, which is non-toxic. As sources of phosphine, for farm use, pellets of aluminium phosphide (AlP), calcium phosphide (Ca 3 P 2), or zinc phosphide (Zn 3 P 2) are used. These phosphides release phosphine upon contact with atmospheric ...
Organophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent.These compounds can be classified according to the value of n: primary phosphines (n = 1), secondary phosphines (n = 2), tertiary phosphines (n = 3).
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. Bisphosphonates are a class of drugs to treat osteoporosis. The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. Phosphinates feature two P–C bonds, with the general formula R 2 P(=O)(OR').
Phosphines or phosphanes are phosphorus compounds derived from phosphine and have the general structure R 3 P. For the nitrogen analogues, please see Category:Inorganic amines . Wikimedia Commons has media related to Phosphines .
The toxicity of sarin in humans is largely based on calculations from studies with animals. The lethal concentration of sarin in air is approximately 28–35 mg per cubic meter per minute for a two-minute exposure time by a healthy adult breathing normally (exchanging 15 liters of air per minute, lower 28 mg/m 3 value is for general population ...
