Product Information

• Product Code：D081009

• English Name：Dotinurad Impurity 9

• English Alias：2,6-dichloro-4-(1,1-dioxido-2,3-dihydrobenzo[d]thiazole-3-carbonyl)phenyl 3-chlorobenzoate

• CAS No.：Not provided

• Molecular Formula：C₂₁H₁₂Cl₃NO₅S

• Molecular Weight：496.75

Advantages

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

• Stability Assurance：Stable for 36 months at -20℃ under light-protected, sealed storage; degradation rate <0.3% in methanol-acetonitrile mixture within 6 months.

Applications

• Quality Control Testing：Used for UPLC-MS/MS detection of Impurity 9 in Dotinurad API and formulations, controlling content to meet ICH Q3A standards (single impurity limit ≤0.1%).

• Process Optimization Research：Monitors impurity formation during Dotinurad synthesis, reducing generation by >30% by adjusting chlorination temperature (e.g., 50-60℃) and reaction time.

• Method Validation：Serves as a standard for developing impurity detection methods, verifying UPLC resolution (≥3.0) and LOD (0.01 ng/mL).

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 8 minutes, with LOD of 0.005 ng/mL for trace impurity analysis.

• Formation Mechanism：Formed by reaction of benzothiazole-3-carboxylic acid derivatives with 3-chlorobenzoyl chloride under chlorinating agents; optimizing agent dosage and reaction pH inhibits side reactions.

• Safety Evaluation：In vitro cytotoxicity shows IC₅₀ of 189.6 μM against HK-2 cells (Dotinurad IC₅₀=10.5 μM), with lower toxicity than the main drug but requiring strict content control. Long-term stability testing is ongoing to monitor degradation under high temperature and humidity conditions.
