Product Information

• Product Code：B201378

• English Name：N-(1-hydroxy-2-methylpropan-2-yl)-N-methylnitrous amide

• English Alias：N-(1-hydroxy-2-methylpropan-2-yl)-N-methylnitrous amide

• CAS No.：27646-81-7

• Molecular Formula：C?H??N?O?

• Molecular Weight：132.16

Advantages

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

Applications

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

• Process Optimization Research：Monitors nitroso impurity formation during target compound synthesis, reducing generation by >40% by adjusting reaction system pH (e.g., neutral to weakly alkaline) and temperature (≤25℃).

• Method Validation：Serves as a standard for developing nitroso 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 5 minutes, with LOD of 0.002 ng/mL for trace analysis of genotoxic impurities.

• Formation Mechanism：Formed by reaction of N-methyl-2-methyl-2-propanamine with nitrite under acidic conditions (e.g., pH <3); optimizing nitrosating agent dosage 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 gastric mucosa at a 10 mg/kg dose. Accelerated stability testing is ongoing to systematically study degradation characteristics and mutagenic risks under high temperature and humidity conditions.
