Precision and Expertise in Chlorhexidine Gluconate Analysis

Chlorhexidine gluconate is a bisguanidine chlorobenzene with a broad spectrum of antimicrobial activity. Chlorhexidine gluconate is also a powerful disinfectant and antimicrobial agent and can be prepared as a solution, gargle, or topical solution for a wide range of pharmaceutical applications. At CD BioGlyco, we provide high-quality chlorhexidine gluconate analysis services with extensive experience in the field of Pharmaceutical Analysis. The services we offer include but are not limited to the following.

• State
  Chlorhexidine gluconate is a clear, colorless slight yellow, and slightly viscous liquid. It is miscible with water and soluble in ethanol or acetone.
• Identification
  • We dilute the sample well with water and copper sulfate solution, then, the solution is boiled to cause the precipitate to coalesce. If a lavender color appears in the solution, the sample is chlorhexidine gluconate.
  • Add ferric chloride solution to an aqueous solution of the sample and heat to boiling. If the solution changes color to yellow, the sample is chlorhexidine gluconate.
  • The sample is added to a hot solution of cetyltrimethylammonium bromide to which a bromine test solution is added along with a sodium hydroxide test solution. If the solution shows a deep red color, the sample is chlorhexidine gluconate.
• Acidity
  The acidity of chlorhexidine gluconate is tested using a pH meter.
• Detection of p-chloroaniline
  We dilute chlorhexidine gluconate well with water, hydrochloric acid, and ethanol and compare the color of the solution with that of a p-chloroaniline solution against a black background. If the colors are identical, p-chloroaniline is present in chlorhexidine gluconate.
  
  • Impurity assay
    A sample of chlorhexidine gluconate is added to the acetic acid solution. Next, the solution is unfolded on the same thin-layer silica gel plate as the solution of chlorhexidine gluconate standard according to wave-layer chromatography. Finally, the thin layer plate is placed under an ultraviolet light for review. If the sample contains stray dots it means that the sample contains impurities.
  • Content assay
    Chlorhexidine gluconate is weighed accurately and diluted with water. Then, we add ethanol solution to it. The absorbance is measured spectrophotometrically. Finally, we calculate the content of chlorhexidine from the absorbance value.
