Carboxylic acid Carboxylic acid A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH). The general formula of a carboxylic acid is R–COOH, with R referring to the rest of the (possibly quite large) molecule. Carboxylic acids occur widely and include the amino acids (which make up proteins) and acetic acid (which is part of vinegar and occurs in metabolism). Salts and esters of carboxylic acids are called carboxylates. When a carboxyl group is deprotonated, its conjugate base forms a carboxylate anion. Carboxylate ions are resonance-stabilized, and this increased stability makes carboxylic acids more acidic than alcohols, along with
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
