Products Description
Introduction and application of CAS：603-45-2| ROSOLIC ACID
Alias of rose acid: resinous acid, rose acid, rose acid, golden red, deep red crystals with metallic luster. Rosaceae acid also has yellow-brown flakes with a dark green metallic appearance. Rosacetic acid is easily soluble in alcohol and presents a golden yellow solution; when soluble in sodium hydroxide or potassium hydroxide solution, it presents a carmine red color; when soluble in concentrated sulfuric acid, 70% sulfuric acid, hydrochloric acid or perchloric acid, it presents a yellow to orange solution; and it is slightly soluble in glacial acetic acid. , slightly soluble in ether and chloroform, almost insoluble in (0.12%) and benzene. Purpose Rose acid can be used as a qualitative reagent for carbon dioxide in drinking water, and can also be used to distinguish human milk from cow milk. Rosacetic acid is also a dye intermediate. The acid belongs to the hydroxytriphenylmethane dye. It has no dyeing value for textile fibers. It is mainly used as an indicator in analytical chemistry. Its pH value discoloration range is 6.2 to 8.0, and the color changes from yellow to red.
