- Trace Impurities.
- Intermediates from the synthesis process.
- By-products of degradation.
- Contamination from equipment.
- Microscopic Analysis: A detailed microscopic examination of the colored particles could provide clues about their nature and origin. Techniques like polarized light microscopy or even more advanced methods might be helpful.
- Spectroscopic Analysis: If enough material can be isolated, techniques like UV-Vis spectroscopy or infrared spectroscopy could help identify the chemical nature of the colored particles.
- Consider the Limits: Review the specific limits for impurities in the Levamisole HCl BP monograph. While it complies with the overall test, there might be limits for specific types of impurities.
