El-Zahraa, F.; El-Basil, S.; El-Sayed, M.; Ghoneim, K. M.; Khalifa, M. published an article on January 31 ,1979. The article was titled 《Synthesis and pharmacological screening of certain N-substituted amides structurally related to some local anesthetics》, and you may find the article in Pharmazie.HPLC of Formula: 70298-88-3 The information in the text is summarized as follows:
Eighteen Ph2CHCONHR (I; R = e.g., 2,6-, 2,5-, 2,4-, 3,4-, 3,5-Me2C6H3, 4,5-MeClC6H3, 4-O2NC6H4) and 14 Me3CCONHR1 (II; R1 = e.g., 3,6-Me2C6H3, 3-pyridyl, 4-nitro-2-pyridyl) were prepared in 45-90% yield by reaction of the acid chloride with the resp. amine. The most active intradermal anesthesia in guinea pigs was I (R = 4-methyl-5-chlorophenyl); its activity was more than double that of procaine hydrochloride. As a corneal anesthetic II (R1 = 2,6-Me2C6H3) was the most active anesthetic and for plexus anesthesia I (R = 2,6-Me2C6H3) was the most active. In the experimental materials used by the author, we found 2,2-Dimehtyl-N-pyridin-3-yl-propionamide(cas: 70298-88-3HPLC of Formula: 70298-88-3)
2,2-Dimehtyl-N-pyridin-3-yl-propionamide(cas: 70298-88-3) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.HPLC of Formula: 70298-88-3
