Chemical Property/Description

Purple or brown black crystal, orange yellow in water, slightly soluble in sodium bicarbonate solution, insoluble in alcohol, the solution is unstable, must be prepared fresh when used.

Stable. Incompatible with strong oxidizing agents.

Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.


Main Uses:

It can be used to test barium, strontium, scandium, lead, tin and sulfate, as an indicator in the determination of barium and sulfate capacity.

Sodium rhodizonate has good thermal stability and solubility, can dissolve in water and form a red solution. It has strong oxidizing and reducing properties, and can be used as an oxidant and reducing agent. In addition, sodium rose rubinate also has fluorescent properties, which can emit red fluorescence under ultraviolet light.

Sodium rhodizonate is mainly used in chemical analysis as an indicator to detect the presence or concentration changes of reducing agents and oxidants. It can also be used in the production of dyes and pigments, and the preparation of red photosensitive materials. In addition, sodium rose rubinate can also be used in the medical field as a laser dye, fluorescent probes and so on.
