Description

Gastrozol CAS NO 79933-26-9 is a high-purity pharmaceutical intermediate, specifically a key building block in the synthesis of advanced active pharmaceutical ingredients (APIs). This compound matters for its critical role in ensuring the efficacy and consistency of final drug formulations, particularly in the gastrointestinal therapeutic area. It is essential for pharmaceutical manufacturers, research institutions, and fine chemical suppliers engaged in the development and production of specialized medications.

Application

• Pharmaceutical Synthesis: Primary use as a crucial intermediate in the manufacture of proton pump inhibitor (PPI) APIs and related gastrointestinal drugs.
• Research & Development: Serves as a reference standard and a starting material in medicinal chemistry for developing new therapeutic agents targeting acid-related disorders.
• Fine Chemical Production: Utilized in multi-step organic synthesis to create complex molecules with specific chiral or functional properties.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for cGMP-compliant production of finished dosage forms.
• Analytical Standards: Used in quality control laboratories for method development, validation, and impurity profiling via HPLC or LC-MS.

Quality Control

Our Gastrozol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and can be tailored to meet specific pharmacopeial requirements (e.g., USP, EP).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
