Chemical Property/Description

Brown green fine crystalline powder, soluble in ethanol,  glacial acetic acid and alkali solution, yellow solution in acetic acid, red purple in dilute lye, slightly soluble in water,Maximum absorption wavelength 579(371)nm


Main Uses:

Used as an acid-base indicator, there are two discoloration ranges, the first discoloration range pH 1.2(red) ~ 2.8(yellow), the second discoloration range pH 7.4(yellow) ~ 9.0(purple).

The main use of 2303-01-7 is as a REDOX indicator for fresh tissue staining (such as tumor, nerve tissue, Nysch granules, blood, etc.)

The alkaline solution is purple, the weakly acidic solution is yellow, and the strongly acidic solution is pink.

2303-01-7 is a kind of bright brown green fine crystalline powder, which is widely used in the field of biological dyeing because of its excellent dyeing properties. It has a strong affinity and can bind the DNA molecules in the nucleus well, making it show a specific color during the dyeing process, so as to display and identify the structure of the nucleus and chromosomes.
