Biotin sulfone

Product Information

• Product Code：B042024

• English Name：Biotin sulfone

• English Alias：5-((3aS,4S,6aR)-5,5-dioxido-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanoic acid

• CAS No.：40720-05-6

• Molecular Formula：C??H??N?O?S

• Molecular Weight：276.31

Advantages

• High-Purity Reference Standard：Confirmed by HPLC (≥99.0%), NMR (1H, 13C), HRMS, and elemental analysis, suitable for Biotin impurity analysis and quality control.

• Stability Assurance：Stable for 36 months at -20℃ under light-protected, sealed storage; degradation rate <0.2% in methanol-water solution within 6 months.

Applications

• Quality Control Testing：Used for UPLC-MS/MS detection of sulfone impurities in Biotin API and formulations, controlling content to meet ICH Q3A standards (single impurity limit ≤0.1%).

• Process Optimization Research：Monitors Biotin sulfone formation during Biotin synthesis or storage, reducing generation by >40% by adjusting oxidation conditions (e.g., temperature ≤30℃, avoiding strong light).

• Metabolic Studies：As the final oxidation product of Biotin in vivo or in vitro, used to study Biotin's oxidative metabolic pathway and assist in evaluating drug stability during storage and metabolism.

Background Description

Research Status

• Detection Technology：UPLC-MS/MS with C18 column (1.7μm) and 0.1% formic acid-acetonitrile gradient elution achieves separation within 5 minutes, with LOD of 0.003 ng/mL for trace impurity analysis.

• Formation Mechanism：Formed by two-step oxidation of Biotin's thioether group, accelerated by light, high temperature, or metal ions (e.g., Fe3?). Inhibition is achieved by adding antioxidants (e.g., vitamin E) or using inert gas protection.

• Safety Evaluation：In vitro cytotoxicity shows IC?? of 215.6 μM against HEK293 cells (Biotin has no significant toxicity), with low toxicity but requiring ≤0.1% control. Long-term stability testing monitors degradation under different humidity (40%-75%RH), light (4500lx), and temperature (25℃/60℃) conditions.
