Description

Hydrindantin is a specialized organic compound widely recognized as a key reagent in biochemical analysis. Its primary commercial value lies in its critical role as a co-reagent in the quantitative determination of amino acids, particularly proline and hydroxyproline, via colorimetric assays. This makes it an essential component for quality control and research laboratories in the pharmaceutical, food science, and biotechnology sectors. Global suppliers and manufacturers rely on consistent, high-purity Hydrindantin to ensure the accuracy and reliability of their analytical procedures.

Application

• Amino Acid Analysis: Primary use as a co-reagent in the colorimetric assay for proline and hydroxyproline, crucial for protein characterization and collagen research.
• Pharmaceutical QC: Used in the quality control testing of raw materials and finished drug products where amino acid content is a critical specification.
• Food & Nutrition Science: Employed in the analysis of protein hydrolysates, collagen peptides, and nutritional supplements to determine specific amino acid profiles.
• Biochemical Research: A vital reagent in life science research for studying collagen metabolism, connective tissue disorders, and protein biochemistry.
• Diagnostic Kits: Incorporated into commercial diagnostic test kits and reagents for clinical and veterinary analysis.
• Industrial Fermentation Monitoring: Applied in bioprocessing to monitor amino acid production in fermentation broths.

Quality Control

Our Hydrindantin is produced and tested under strict quality management systems to ensure it meets the exacting standards required for analytical applications. Each batch undergoes comprehensive analysis, including purity assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting all test results are available upon request, providing full traceability and compliance data for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere for long-term stability and to minimize degradation. Keep away from strong oxidizing agents.
