Description

Diphenylethanone Impurity 2 CAS NO 23464-17-7 is a high-purity chemical reference standard used for analytical and research purposes. This compound is critical for quality control and method development in pharmaceutical manufacturing, ensuring the safety and efficacy of active pharmaceutical ingredients (APIs). It is primarily required by analytical laboratories, R&D facilities, and quality assurance departments within the pharmaceutical and fine chemical industries.

Application

• Pharmaceutical Impurity Profiling: Serves as a certified reference material (CRM) for the identification and quantification of related substances in Diphenylethanone (Benzil) and its derivative APIs.
• Analytical Method Development and Validation: Used as a known impurity standard to develop, calibrate, and validate chromatographic methods like HPLC and GC.
• Quality Control (QC) Testing: Essential for in-process testing and release testing of pharmaceutical batches to monitor impurity levels against regulatory thresholds.
• Stability Studies: Employed as a marker compound to track degradation pathways and establish shelf-life for pharmaceutical products.
• Regulatory Compliance and Submissions: Provides necessary data for regulatory filings (e.g., FDA, EMA) to demonstrate thorough impurity characterization.
• Chemical Research: Used in academic and industrial research focused on organic synthesis, reaction mechanism studies, and photochemistry involving benzil derivatives.
