Upon treatment with an alcohol, an isocyanate forms a urethane linkage: ROH + R'NCO → ROC(O)N(H)R' where R and R' are alkyl or aryl groups. If a diisocyanate is treated with a compound containing two or more hydroxyl groups, such as a diol or a polyol, polymer chains are formed, which are known as polyurethanes.
Methyl isocyanate (MIC) is an organic compound with the molecular formula CH 3 NCO. Synonyms are isocyanatomethane and methyl carbylamine.Methyl isocyanate is an intermediate chemical in the production of carbamate pesticides and Haffmann Bromamide Degradation (such as carbaryl, carbofuran, methomyl, and aldicarb).
The primary treatment for megavitamin-B 6 syndrome is to stop taking supplemental vitamin B 6. [14] Physical therapy, including vestibular rehabilitation, has been used in attempts to improve recovery following cessation of vitamin B 6 supplementation. [51] [11] Medications such as amitriptyline have been used to help with neuropathic pain. [19]
Kidney toxicity [5] associated with kidney failure; associated with development of cancer, particularly of the urinary tract, known carcinogen [8] [9] Atractylate Atractylis gummifera: Liver damage, [3] nausea, vomiting, epigastric and abdominal pain, diarrhoea, anxiety, headache and convulsions, often followed by coma [10]
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
Melamine cyanurate forms spoke-like crystals from aqueous solutions [3] and has been implicated as a causative agent for toxicity seen in the Chinese protein export contamination and the 2007 pet food recall. [3] This complex is cited as an example of supramolecular chemistry. [4]
Pulmonary toxicity is the medical name for side effects on the lungs. Although most cases of pulmonary toxicity in medicine are due to side effects of medicinal drugs, many cases can be due to side effects of radiation (radiotherapy). Other (non-medical) causes of pulmonary toxicity can be chemical compounds and airborne particulate matter.
