High-quality Aurothioglucose Analysis with Reliable Results

Aurothioglucose (C₆H₁₁AuO₅S) is a derivative of glucose. CD BioGlyco has professional analysts to provide clients with standard Pharmaceutical and Biological Analysis services. Our lab provides various Pharmaceutical Analysis services such as Anticoagulant Citrate Dextrose Analysis and Dextrose Analysis. We mainly provide two types of analysis services including aurothioglucose analysis and aurothioglucose injectable suspension analysis.

• Aurothioglucose analysis
  • Identification
    Our researchers use thin-layer chromatography (TLC) to identify aurothioglucose. First, a standard solution of aurothioglucose is prepared as A. Take trace amounts of A and aqueous standard aurothioglucose solution spot on the TLC glass microfilament pieces. Then, display in a solvent system containing a mixture of n-propyl alcohol, water, and ethyl acetate. Finally, we examine the spots under ultraviolet (UV) light waves and provide correspondence between the radio frequency (R_F) values of the measured solution and the standard solution.
    In addition, we judge the presence of aurothioglucose through the presence of heavy and white precipitation observed by adding barium chloride to part of the filtrate.
  • Specific rotation
    We provide accurate specific rotation measurement service. Our company is very concerned about the reliability of the data, so we repeat the test many times and average the rotation value.
  • Loss on drying
    We use the phosphorus pentoxide dried sample for 24 h and test for loss of weight.
  • Content
    We detect the weight of gold in solution through a series of operations such as quantitative dissolution, addition of nitric acid, boiling, filtration, rinsing, drying, and ignition. Then, we calculate the weight of C₆H₁₁AuO₅S in the portion of aurothioglucose taken.
• Aurothioglucose injectable suspension analysis
  • Identification
    We analyze aurothioglucose injectable suspension by high-performance liquid chromatography (HPLC). Our researchers mix aurothioglucose injectable suspension, ethyl acetate, and water, centrifug the supernatant, and use liquid phase separation.
  • Bacterial endotoxins test
    We provide aurothioglucose sterility tests to analyze endotoxin units.
  • Content
    We calculate the weight of C₆H₁₁AuO₅S in the portion of injectable suspension taken to pass the test for the gold content by adding acetone and nitric acid.
