Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
Potassium amyl xanthate (/pəˈtæsiəm ˌæmɪl ˈzænθeɪt/) is an organosulfur compound with the chemical formula CH 3 (CH 2) 4 OCS 2 K. It is a pale yellow powder with a pungent odor that is soluble in water.
There are several benefits to using muscle pain relief creams: Reduced inflammation: "Some creams may contain anti-inflammatory agents like NSAIDs (e.g., diclofenac) that can reduce localized ...
Diasorin S.p.A. is an Italian multinational biotechnology company that produces and markets in vitro diagnostics reagent kits used in immunodiagnostics and molecular diagnostics and since July 2021, it is also active in the Life Science business.
Ehrlich's reagent or Ehrlich reagent is a reagent containing p-dimethylaminobenzaldehyde (DMAB) and thus can act as an indicator to presumptively identify indoles and urobilinogen. Several Ehrlich tests use the reagent in a medical test ; some are drug tests and others contribute to diagnosis of various diseases or adverse drug reactions .
Diisopropyl azodicarboxylate (DIAD) is the diisopropyl ester of azodicarboxylic acid. It is used as a reagent in the production of many organic compounds.It is often used with triphenylphosphine in the Mitsunobu reaction, [2] wherein it serves as a hydride acceptor.
In basic solutions (pH > 10), rhodizonic acid quickly converts to the THBQ anion (CO) 4− 6 in the absence of oxygen, and to croconic acid in its presence. At pH 8.3 and exposure to light, solutions are stable for days in the absence of oxygen, and decompose to croconic acid and other products (possibly including cyclohexanehexone or ...
It is always used as a solvate, e.g., with tetrahydrofuran or dimethoxyethane, which bind to the sodium cation. [1] An oxygen-sensitive colourless solid, it is a reagent in organometallic and organic chemical research. The dioxane solvated sodium salt is known as Collman's reagent, in recognition of James P. Collman, an early popularizer of its ...
