Ethyl cyanohydroxyiminoacetate (oxyma) is the oxime of ethyl cyanoacetate and finds use as an additive for carbodiimides, such as dicyclohexylcarbodiimide (DCC) in peptide synthesis. It acts as a neutralizing reagent for the basicity or nucleophilicity of the DCC due to its pronounced acidity ( pKa 4.60) and suppresses base catalyzed side ...
In a reciprocating engine, the use of water injection, also called anti-detonation injection or ADI, is used to prevent engine knocking also known as "detonation". [3] Commonly found on large radial engines with pressure carburetors , it is a mixture of water and alcohol injected into the carburetor at high power settings.
A sterile version is used for making solutions that will be given by injection. [2] Before such use other substances generally must be added to make the solution isotonic. [3] Isotonic solutions containing water for injection can be given by injection into a vein, muscle, or under the skin. [4] A non-sterile version may be used in manufacturing ...
Methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate is an organic compound used in sunscreens to absorb UVA radiation. It is marketed as Mexoryl 400 by L'Oréal . MCE has an absorption maximum of 385 nm, which is in the long-wave UVA range ( UVA1 , 360−400 nm).
Drug companies have made it harder to buy midazolam for executions. The etomidate was followed by rocuronium bromide, a paralytic, and finally, potassium acetate in place of the commonly used potassium chloride injection to stop the heart. Potassium acetate was first used for this purpose inadvertently in a 2015 execution in Oklahoma. [24]
Etamsylate is a haemostatic agent; also promotes angioprotective and proaggregant action. It stimulates thrombopoiesis and their release from bone marrow. Haemostatic action is due to activation of thromboplastin formation on damaged sites of small blood vessels and decrease of PgI2 (Prostacyclin) synthesis; it also facilitates platelet aggregation and adhesion, that at last induce decrease ...
Ethyl cyanoacetate is a building block for the synthesis of heterocycles which are used for example as drugs: Allopurinol , used for the treatment of chronic gout, can be synthesized starting with a Knoevenagel condensation with triethyl orthoformate ; the condensation product is cyclized with hydrazine to give a substituted pyrazole and ...
In gastroenterology, butyl cyanoacrylate is used to treat bleeding gastric varices, which are dilated veins that occur in the setting of liver cirrhosis or thrombosis of the splenic vein. [7] The gastric varices are accessed by endoscopy, which uses a flexible fibre-optic camera to enter the stomach. They are injected with a catheter needle ...
