Molecular Formula	C29H20ClN7O11S3
Molar Mass	774.16
Physical and Chemical Properties	Dark blue black powder. The solubility in water (50 ℃) is 30g/L. The aqueous solution is red and bright blue, and the addition of 1mol/L sodium hydroxide is still bright blue. After adding sodium sulfite and warming it to orange brown, the addition of sodium perborate is still orange brown. It is dark blue-purple in concentrated sulfuric acid, and turns blue after dilution; it is yellow-brown in concentrated nitric acid, and turns light brown after dilution.

Use	reactive brilliant blue K-GR can be used for dyeing cotton and viscose fibers with low affinity and good levelness, poor deep dyeing, preferably light blue. It is mainly used for direct printing of cotton and viscose fabrics. Due to its low affinity, the unfixed dye is easy to wash. It can also be used for direct printing of silk. It can also be used for dyeing wool and direct printing of wool fabric and nylon fabric. The two-bath dyeing of polyester/cotton blended fabric can be combined with reactive bright yellow K-4G, reactive brilliant orange K-GN, reactive brilliant red K-2G and reactive brilliant red K-2BP in medium and deep color. When dyeing viscose blended fabric, polyester, acrylic fiber and triacetate fiber do not stain, diacetate fiber and nylon stain seriously, and wool stain seriously. printing for cotton, hemp, viscose and other fabrics
production method	with bromamine acid, 2, 4-diaminobenzenesulfonic acid, cyanuric chloride and M-aminobenzenesulfonic acid as raw materials, first, the Bromo acid is condensed with 2, 4-diaminobenzenesulfonic acid, then condensed with cyanuric chloride, and finally condensed with M-aminobenzenesulfonic acid to obtain a product, which is subjected to salting-out, filtration and drying to obtain a finished product..
