Description

Imp CAS NO 131-99-7 is a high-purity chemical intermediate essential for advanced synthesis and research. This compound is critical for ensuring the quality and consistency of downstream products in regulated industries. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for process development and quality control applications.

Application

• Pharmaceutical Impurity Standard: Used as a certified reference material (CRM) for the identification and quantification of impurities in active pharmaceutical ingredients (APIs) and finished drug products.
• Analytical Research: Serves as a critical standard in High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), and Mass Spectrometry (MS) for method development and validation.
• Process Chemistry: Employed in route scouting and optimization studies to understand and control impurity profiles during chemical synthesis.
• Quality Assurance/Quality Control (QA/QC): Integral for establishing specifications and ensuring batch-to-batch consistency in chemical manufacturing.
• Regulatory Compliance: Supports regulatory filings (e.g., for FDA, EMA) by providing characterized impurity data for drug master files (DMFs) and investigational new drug (IND) applications.
