Diosmin

Diosmin Impurities

Diosmin is a naturally occurring flavonoid glycoside derived from hesperidin, widely used in the treatment of chronic venous insufficiency, hemorrhoids, and vascular disorders. Its impurity profile includes structurally related flavonoid analogs, residual solvents, and degradation products formed under stress conditions such as hydrolysis, oxidation, and photolysis. Degradation pathways typically involve oxidative breakdown of the flavone backbone, hydrolytic cleavage of the glycosidic bond, and rearrangement of the phenolic substituents. These impurities may affect the drug’s potency, stability, and safety. All impurities are structurally characterized and qualified in accordance with ICH guidelines for toxicological assessment and analytical validation.

Diosmin EP Impurities

Pharmacopeial and non-pharmacopeial Diosmin impurity compounds are available in compliance with European Pharmacopoeia (EP) specifications. These standards support analytical method development, impurity profiling, and long-term stability studies. EP traceable materials are supplied with validated analytical data, including purity, structural confirmation, and spectral characterization.

Diosmin Related Compounds

Structurally related compounds and synthetic analogs associated with Diosmin are included for use in impurity identification, toxicological qualification, and regulatory submission. These related substances are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations. They are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Diosmin Impurity Reference Standards

Diosmin impurity reference standards are provided with validated analytical data, including purity, NMR, MS, and full Certificates of Analysis. These standards are used in pharmaceutical research, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
