8] synthesized a novel nitrogen-phosphorus flame retardant CMA by using 2-carboxyethyl(phenyl) phosphinic acid reacting with melamine in aqueous solution, and prepared halogen-free flame retardant flexible polyurethane foams by filling CMA, results showed that CMA endowed polyurethane with good flame resistance.
Sulphadimidine 33%, Sodium salt of 4 dimethylamino 2 methylphenyl phosphinic acid
For example, similar to the case made by the FMC for butyllithium, the sponsor for benzene phosphinic acid (phenylphosphinic acid) proposed no additional mammalian toxicology testing because existing animal data showed that administration by oral gavage causes gastrointestinal tract bleeding, necrosis, and occasionally perforation, and the corrosive effects of this substance had already been demonstrated as the basis for its toxicity (BPD/BPA Coalition 2003).
The new facility doubles the capacity for DEPAL (diethyl phosphinic acid aluminum salt)-based FRs.
Rat liver injury after normothermic ischemia is prevented by a phosphinic matrix metalloproteinase inhibitor.
Under the theme of biochemistry and disease, it discusses such topics as biosynthesis of phosphonic and phosphinic acid natural products, new antivirals and drug resistance, multidrug resistance in bacteria, conformational pathology of the serpins, and prions.

Included are Clariant's ammonium polyphosphate (APP)-based intumescent FRs for polyolefins, Exolit AP 750 and Exolit AP 752; red phosphorus, an effective FR for glass-filled polyamides, thermoset resins, and polyolefin wire/cable compounds; and the organo phosphinates, a new class of FR technology consisting of a metal salt of adialkyl phosphinic acid in combination with proprietary nitrogen-containing compounds.
A thermoplastic pellet form of a phosphinic PET copolymer (6% phosphorus), EniFlam 6P behaves like a halogen in that it shows FR activity in both the vapor and solid phase (PT, March '93, p.
g]) P-glass, phosphinic acid salt, zinc salt, and melamine salt, and have reported that it has a combination of improved physical and flame resistance properties.
Half-lives were recently determined for the di-substituted perfluoroalkyl phosphinic acids (diPFPAs) in both male and female rats (D'eon and Mabury 2010).
