Description

Pregabalin Impurity 18 is a high-purity reference standard used for analytical and research purposes. This compound is critical for ensuring the quality, safety, and regulatory compliance of the active pharmaceutical ingredient (API) pregabalin. It is primarily required by pharmaceutical manufacturers, analytical laboratories, and regulatory bodies for method development, validation, and impurity profiling studies.

Application

• Pharmaceutical Impurity Profiling: Used as a certified reference material for the identification and quantification of specific impurities in pregabalin API and finished dosage forms.
• Analytical Method Development & Validation: Serves as a critical standard for developing and validating HPLC, UPLC, or LC-MS methods to monitor impurity levels.
• Quality Control & Assurance (QC/QA): Essential for in-process testing and release testing of pregabalin batches to ensure they meet pharmacopeial specifications (e.g., USP, EP).
• Stability Studies: Employed to track the formation of this impurity over time under various stress conditions, supporting drug shelf-life determination.
• Regulatory Submissions: Provides necessary data for drug master files (DMFs), investigational new drug (IND) applications, and new drug applications (NDAs).
• Research & Development: Used in synthetic chemistry research to study the degradation pathways and metabolism of pregabalin.
