Qufu Focuschem Trading Co.,Ltd | Updated: Sep 20, 2017

      Chondroitin sulfate is a kind of acidic polysaccharide material extracted from animal tissues, which is white or off-white powder; The aqueous solution of this product is viscous and does not condense. This product in water soluble, insoluble in ethanol, acetone, and ether and other organic solvents, its salts to heat more stable, heat up to 80 ℃ also not be destroyed. Chondroitin sulfate aqueous solution, in the event of higher temperature or acid is unstable, mainly the deacetylation or degradation of monosaccharides or small molecular weight of polysaccharides.Chondroitin Sulfate

     This product is white or off-white powder, slightly salty, odorless and wet. The aqueous solution of this product is viscous and does not condense. This product is soluble in water and insoluble in ethanol, acetone or glacial acetic acid. The infrared light absorption atlas of this product should be consistent with the Atlas of Chondroitin sulfate sodium (appendix IV C). Chondroitin Sulfate

     The area ratio of chondroitin sulfate A and C in the determination of this product content should be 5.0 ~ 6.0. The differential reaction of sodium salt in aqueous solution of this product (appendix II). The ratio of rotation to take this product, precision, water dissolved and quantitative diluted into 1ml per 40mg solution. In accordance with the Law (appendix Ⅵe), the ratio of rotation should be -28° to -33°.Chondroitin Sulfate

     Absorbance to take this product, the use of water for each 1ml containing 4mg solution, according to Ultraviolet Spectrophotometry (appendix Ⅳa) determination, at 260nm wavelength, its absorbance must not be greater than 0.18, at 280nm Wavelength, its absorbance must not be greater than 0.10. Chondroitin Sulfate

      The residual residue under the burning residue of heavy metals is determined by the heavy Metal inspection method (Appendix Ⅷh second method), which contains no more than twenty out of 10,000 heavy metals. residual solvents to take this product, according to law inspection (appendix Ⅷp), the content of ethanol should not exceed 0.5%.Chondroitin Sulfate
