Salicylic acid 4-aminosalicylic acid, sandulpiride, and landetimide (via Salethamide). Salicylic acid was one of the original starting materials for making acetylsalicylic acid (aspirin) in 1897. Bismuth subsalicylate, a salt of bismuth and salicylic acid, is the active ingredient in stomach relief aids such as Pepto-Bismol, is the main ingredient of Kaopectate and "displays anti-inflammatory action (due to salicylic acid) and also acts as an antacid and mild antibiotic". Other derivatives include methyl salicylate used as a liniment to soothe joint and muscle pain and choline salicylate used topically to relieve the pain of mouth ulcers. Salicylic acid has the formula CH(OH)COOH, where
Vinylphosphonic acid known for promoting adhesion between organic and inorganic phases. Such interfaces exist between coatings and the substrates to which they are applied. Both vinylphosphonic acid homopolymer and its copolymers are the basis of many products which have found applications in scale and corrosion treatment. Polyvinylphosphonic acid is an essential component for the polymer electrolyte membranes used in fuel cell development, in the medical field as dental cements, hydrogels for drug delivery, and components in biomimetic mineralization. Vinylphosphonic acid Vinylphosphonic acid is an organophosphorus compound with the formula CHPOH. It is a colorless, low-melting solid although commercial samples are often yellowish
