quality
Vat red 41 is a synthetic organic dye also known as bromophenol red. Its chemical name is 2-hydroxy-1-[(2Z)-2-(4-nitroaniline)-2-enyl]benzoazo-3-one.

Vat Red 41 is a red powdered dye that is soluble in water, ethanol and ether solvents. It has good stability to light and is not easy to fade. In acidic conditions, it has a vivid red color, while in alkaline conditions it appears brownish-yellow. This dye shows good hydrophilicity and fibrophilic properties and can be used to dye fibrous materials such as textiles and leather.

Vat Red 41 has a wide range of applications. Due to its brilliant colors and good light stability, it is widely used in textiles, paper, plastics, coatings and inks. Vat red 41 is also used as a biological dye and fluorescent probe for microscopic examination of cells and tissues.
During use and handling, safe operating procedures should be strictly followed and contact with the skin and inhalation should be avoided.
