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 ...
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 ...
Established in 2002, the Canadian International Pharmacy Association ("CIPA") is a Canadian association of licensed pharmacy businesses offering mail order pharmacy services to Canadian and international patients. CIPA members sell pharmaceuticals and maintenance medications to individuals upon receipt of a valid prescription.
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).
The Compendium of Pharmaceuticals and Specialties: The Canadian Drug Reference for Health Professionals, more commonly known by its abbreviation CPS, [1] is a reference book that contains drug monographs and numerous features which help healthcare professionals prescribe and use drugs safely and appropriately.
Phosphine oxide is the inorganic compound with the formula H 3 PO. Although stable as a dilute gas, liquid or solid samples are unstable. Unlike many other compounds of the type PO x H y, H 3 PO is rarely discussed and is not even mentioned in major sources on main group chemistry.
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 first reported phosphine complexes were cis- and trans-PtCl 2 (PEt 3) 2 reported by Cahours and Gal in 1870. [5] Often the phosphine serves both as a ligand and as a reductant. This property is illustrated by the synthesis of many platinum-metal complexes of triphenylphosphine: [6] RhCl 3 (H 2 O) 3 + 4 PPh 3 → RhCl(PPh 3) 3 + OPPh 3 + 2 ...
