Product Information

• Product Code：N031165

• English Name：N-Nitroso Olodaterol

• English Alias：(R)-N-(2-hydroxy-2-(6-hydroxy-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazin-8-yl)ethyl)-N-(1-(4-methoxyphenyl)-2-methylpropan-2-yl)nitrous amide

• CAS No.：Not provided (to be supplemented)

• Molecular Formula：C₂₁H₂₅N₃O₆

• Molecular Weight：415.44

Advantages

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

• Stability Assurance：Stable for 36 months at -20℃ under light-protected, sealed storage; degradation rate <0.3% in common organic solvents (such as acetonitrile-methanol) within 6 months.

Applications

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

• Process Optimization Research：Monitors impurity formation during Olodaterol synthesis, reducing generation by >40% by adjusting nitrosation temperature (e.g., 0-5℃) and pH.

• 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 nitrosation of amino groups in Olodaterol with nitrites under acidic conditions (e.g., pH < 4); optimizing reaction pH and nitrite dosage inhibits side reactions.

• Safety Evaluation：In vitro cytotoxicity shows IC₅₀ of 178.3 μM against BEAS-2B cells (Olodaterol IC₅₀=8.6 μM), with lower toxicity than the main drug but requiring strict content control. Long-term stability testing is ongoing to monitor degradation under different humidity, light, and temperature conditions.
