  Character
  
  This product is white or white powder or crystalline powder; slight special smell.
  
  This product is slightly soluble in water (1g/35mL), slightly soluble in ethanol, methanol or chloroform.
  
  Identify
  
  (1) take this product about 5mg, addition of sodium hydroxide solution 2.5ml dissolved, add potassium ferricyanide solution 0.5
  
  Ml 5ml and n-butanol, strong shake for 2 minutes, placed, so that stratification, alcohol layer show strong blue fluorescence; and
  
  Acid to the acidic, fluorescence disappears; add alkali alkalize, fluorescence and show.
  
  (2) take this product is about 10mg, a test tube, add 1ml of water so that dissolved, add an equal amount of sulfuric acid, pay attention to mix, put cold
  
  After the addition of ferrous sulfate solution along the tube wall, the two liquid layer, interface was brown.
  
  (3) take this product about 10mg, add 10ml of water, dissolving, adding sulphuric acid and copper (or copper scrap), heating, which happened
  
  Steam red brown.
  
  (4) the goods should be light absorption pattern contrast pattern of (spectrum set of 476 plans) consistent.
  
  Check
  
  The pH to take this product 0.20g, add 10ml of water dissolved, according to the determination of (Appendix VI H), pH
  
  Value should be 6 ~ 7.5. The clarity and color of solution to take this product 1.0g, add new boiled cold water dissolved in 50ml,
  
  The solution should be clear and colorless; such as color, and Yellow No. 1 standard color solution (Appendix A first law) comparison, not deeper.
  
  Chloride to take this product 0.10g, to check (Appendix VIII A), made with standard solution of sodium chloride 6.0mL
  
  The control liquid, not more concentrated (0.06%).
  
  Loss on drying take this product, at a temperature of 105 DEG C dried to constant weight loss weight shall not exceed 1% (Appendix VIII L).
  
  Residue on ignition shall not exceed 0.1% (Appendix VIII N).
  
  Determination of content
  
  Take this product about 0.14g, accurately weighed, adding anhydrous formic acid 5ml dissolved, add acetic anhydride 70ml,
  
  As the potentiometric titration (Appendix VII A), with perchloric acid titration solution (0.1mol/L) titration, and the titration node
