Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.Category: pyridine-derivatives

Category: pyridine-derivativesOn September 5, 2007 ,《Facile derivatization of pyridyloxazole-type fluorophore via click chemistry》 was published in Chemistry Letters. The article was written by Shi, Jing; Liu, Lei; He, Jing; Meng, Xiangming; Guo, Qingxiang. The article contains the following contents:

New derivatives of the arylpyridyloxazole-type fluorophore were synthesized in high efficiency through click chem. This method is potentially useful for the combinatory screening of fluorescent labels to target specific biol. processes. Using this method, we successfully developed three new pyrazole ratiometric dual-fluorescent pH sensors.4-Ethynylpyridin-2-amine(cas: 1094679-27-2Category: pyridine-derivatives) was used in this study.

4-Ethynylpyridin-2-amine(cas: 1094679-27-2) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.HPLC of Formula: 1094679-27-2

Ni, Ming Hong; Esposito, Emiliano; Castorina, Massimo; Dal Pozzo, Alma published an article in Letters in Drug Design & Discovery. The title of the article was 《Novel RGD peptidomimetics embedding 1,2,3-triazole as central scaffold; synthesis and αvβ3 integrin affinity》.HPLC of Formula: 1094679-27-2 The author mentioned the following in the article:

Ten new RGD (Arginine-Glycine-Aspartic acid) peptidomimetics have been synthesized and screened for their affinity to αvβ3 integrin receptor. Arginine and Aspartic acid mimetic subunits were connected through 1,2,3-triazole as central scaffold by click chem., affording the final products with good yields. Among them, compounds 3f-j exhibited high affinity to the receptor, with IC50 in the low nanomolar range, comparable to that of the reference compound Cilengitide. The experimental process involved the reaction of 4-Ethynylpyridin-2-amine(cas: 1094679-27-2HPLC of Formula: 1094679-27-2)
