Rocuronium Impurity G (CAS 119302-20-4) is a related substance and reference impurity associated with rocuronium, a non-depolarizing neuromuscular blocking agent. It is primarily used as an analytical reference material for pharmaceutical quality control, impurity profiling, and research related to rocuronium formulations.

Specifications:
- Appearance: White crystalline powder
- Identification (HPLC): The retention time of the major peak in the chromatogram of the sample preparation corresponds to that in the chromatogram of the standard preparation, as obtained in the purity test
- Specific Rotation: [α] +85.0° to +89.0°
- Melting Point: 212–219°C
- Purity: ≥98.5%
- Water: ≤3.0%

Applications:
1. Pharmaceutical Industry: Used as a reference standard for the development, validation, and quality control of rocuronium-based pharmaceutical products.
2. Analytical & Quality Control: Applied in impurity identification, chromatographic method development, stability studies, and regulatory testing of active pharmaceutical ingredients (APIs).
3. Drug Research & Development: Used in pharmaceutical research to evaluate degradation pathways, process-related impurities, and manufacturing consistency.
4. Laboratory Applications: Serves as a valuable analytical tool in pharmaceutical laboratories for structural characterization and comparative studies.

This is a high-purity analytical reference standard for pharmaceutical quality control applications.
