Product Code：N031232
English Name：N-Nitroso Terbutaline
English Alias：N-(tert-butyl)-N-(2-(3,5-dihydroxyphenyl)-2-hydroxyethyl)nitrous amide
CAS No.：Not provided
Molecular Formula：C₁₂H₁₈N₂O₄
Molecular Weight：254.28
High-Purity Reference Standard：Confirmed by HPLC (≥99.0%), NMR (1H, 13C), HRMS, and elemental analysis, suitable for Terbutaline nitroso impurity analysis and quality control.
Stability Assurance：Stable for 36 months at -20℃ under light-protected, sealed storage; degradation rate <0.3% in methanol-water mixture within 6 months.
Quality Control Testing：Used for UPLC-MS/MS detection of N-nitroso impurities in Terbutaline API and formulations, controlling content to meet ICH Q3A standards (single impurity limit ≤0.1%).
Process Optimization Research：Monitors nitroso impurity formation during Terbutaline synthesis, reducing generation by >40% by adjusting reaction system pH (e.g., neutral to weakly alkaline) and temperature (≤30℃).
Method Validation：Serves as a standard for developing nitroso impurity detection methods, verifying UPLC resolution (≥3.0) and LOD (0.01 ng/mL).
Terbutaline, a selective β₂-adrenergic receptor agonist, is used for treating bronchial asthma, chronic bronchitis, and other respiratory diseases by relaxing bronchial smooth muscle. N-Nitroso Terbutaline, a potential genotoxic impurity (GTI), may originate from side reactions between amine compounds and nitrosating agents during production. Nitroso compounds have potential carcinogenicity, and their nitrosamide groups and hydroxyphenyl groups may enhance interaction with DNA, making control of this impurity critical for drug safety.
Detection Technology：UPLC-MS/MS with C18 column (1.7μm) and 0.1% formic acid-acetonitrile gradient elution achieves separation within 7 minutes, with LOD of 0.002 ng/mL for trace analysis of genotoxic impurities.
Formation Mechanism：Formed by reaction of Terbutaline's secondary amine group with nitrite under acidic conditions (e.g., pH <4); optimizing nitrosating agent residue control and post-reaction processing inhibits formation.
Safety Evaluation：In vitro Ames test shows potential mutagenicity, and in vivo mouse model tests demonstrate DNA adduct formation in lung tissue at a 5 mg/kg dose. Accelerated stability and forced degradation tests are ongoing to systematically study degradation pathways and mutagenic risks under light, heat, and oxidation conditions.
