Folin's reagent or sodium 1,2-naphthoquinone-4-sulfonate is a chemical reagent used as a derivatizing agent to measure levels of amines and amino acids. [1] The reagent reacts with them in alkaline solution to produce a fluorescent material that can be easily detected.
Many primary and secondary amines react with carbon disulfide and sodium hydroxide to form dithiocarbamate salts: [2] R 2 NH + CS 2 + NaOH → R 2 NCS 2 − Na + + H 2 O. A wide variety of secondary amines give the corresponding dtc ligand. Popular amines include dimethylamine (Me 2 NH), diethylamine (Et 2 NH), and pyrrolidine ((CH 2) 4 NH ...
Despite the low reactivity of the tetrafluoroborate anion in general, BF − 4 serves as a fluorine source to deliver an equivalent of fluoride. [2] The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known example of such a reaction. [3]
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis.
Boar–pig hybrid is a hybridized offspring of a cross between the Eurasian wild boar (Sus scrofa scrofa) and any domestic pig (Sus scrofa domesticus). Feral hybrids exist throughout Eurasia, the Americas, Australia, and in other places where European settlers imported wild boars to use as game animals.
Of the 700 million cats in the world, an estimated 480 million are feral. [3] [4] [5] Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. [6] [7] They are included in the list of the world's 100 worst invasive alien species. Attempts to control feral cat populations ...
