Over 80-years, 24 sulfate salts were approved and presented in Figs. 4–6. These salts are categorized based on the chemical class of API, such as amino-heterocycles, alkylamines, guanidines, amino sugars, and peptides. Hydroxychloroquine (HCQ) is an amino-heterocycle class of API ...

ABIETIC ACID reacts exothermically with bases, both organic (for example, the amines) and inorganic. Can react with active metals to form gaseous hydrogen and a metal salt. Such reactions are slow if the solid acid remains dry. Can react with cyanide salts to generate gaseous hydrogen cyanide...
Acid or alternately base species concentration in aqueous and non-aqueous samples is quantitated, in the presence of interfering ionic salts, using most preferably differential conductivity detection combined with ion-exchange derivatization, wherein characteristically the acid or base species is derivatized...
Phosphorous acid reacts exothermically with bases. May react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain classes of organic compounds. Reacts with cyanide compounds to release gaseous hydrog...
Acrylic acid is a strong corrosive agent to many metals, such as unalloyed steel, copper, and brass. Frequently the hydrolysis of such metallic materials generates a deep discoloration in acrylic acid. Polyvalent metal salts formed during hydrolytic reactions could also induce polymerization. Therefore...
1. Chemistry Any of a class of compounds that contain hydroxyl ions (OH) and are capable of neutralizing acids in solution. They react with acids and certain metals to form water and salts. Bases turn red litmus paper blue, have a bitter taste, and have a pH of greater than 7. Compare...
