Product Name:Litmus
English Name:Litmus
CAS No.:1393-92-6
Aliases:Litmus indicator, Color reagent
Molecular Formula:C7H7O4N
Physical Properties:Blue-purple powder; a blue pigment extracted from lichen plants. Partially soluble in water, giving a purple solution; soluble in ethanol, insoluble in ether, chloroform and other organic solvents. It is a weak organic acid with a relative molecular mass of about 3300. The color changes due to conjugated structural transformation under different acid-base conditions, with a color-change range of pH 4.9-8.1.
Uses:Litmus is a common acid-base indicator used for endpoint determination in acid-base titrations and rapid testing of solution acidity/alkalinity. It is also used to prepare litmus paper and serves as a dyeing and color-developing agent in chemical analysis.
Technical Specifications:
Purity ≥99%
Relative molecular mass ≈3300
Color-change range pH 4.9-8.1 (red in acid, blue in alkali)
Package specification: 20kg/drum
Appearance: blue-purple powder
