Dobutamine Impurity

Product Information

Product Code：D044044
English Name：Dobutamine Impurity 44
English Alias：2-(3-hydroxy-4-methoxyphenyl)acetonitrile
CAS No.：4468-58-0
Molecular Formula：CHNO
Molecular Weight：163.17

Advantages

High-Purity Reference Standard：Confirmed by HPLC (≥99.0%), NMR (1H, 13C), and HRMS, suitable for precise analysis of Dobutamine impurities.
Stability Assurance：Stable for 24 months at 2-8℃ under light-protected, sealed storage; degradation rate <0.3% in methanol solution within 1 month.

Applications

Quality Control Testing：Used for HPLC and LC-MS detection of Impurity 44 in Dobutamine API and formulations, controlling impurity content to meet ICH Q3A standards (≤0.1%).
Process Optimization Research：Monitors impurity formation during Dobutamine synthesis, reducing generation by >50% by adjusting cyanidation temperature (e.g., 25-30℃) and cyanide reagent dosage.
Method Validation：Serves as a standard for developing impurity detection methods, verifying HPLC resolution (≥2.0) and LOD (0.01 ng/mL).

Background Description

Dobutamine, a β-adrenergic receptor agonist, is used in treating heart failure and other cardiovascular diseases. Impurity 44 may originate from cyanidation side reactions of phenolic compounds during Dobutamine synthesis. The hydroxyl and methoxy groups in its structure may affect drug stability and efficacy. With stricter FDA requirements for cardiovascular drug impurity control, studying such process impurities is key to ensuring drug quality.

Research Status

Detection Technology：UPLC-MS/MS with C18 column (1.7μm) and 0.1% formic acid-acetonitrile gradient elution achieves separation within 2 minutes, with LOD of 0.002 ng/mL for trace analysis.
Formation Mechanism：Formed by reaction of 3-hydroxy-4-methoxybenzaldehyde with sodium cyanide under alkaline conditions; optimizing reaction pH (8.0-9.0) and time (≤3h) inhibits side reactions.
Safety Evaluation：In vitro cytotoxicity shows IC of 205.6 μM against H9c2 cardiac cells (Dobutamine IC=15.6 μM), with low toxicity but requiring ≤0.1% limit. Long-term stability testing is ongoing for degradation monitoring.
