Description

δ-n-Hydroxyornithine is a non-proteinogenic amino acid derivative of ornithine, featuring an additional hydroxyl group on the delta carbon. This structural modification makes it a valuable chiral building block and intermediate in advanced organic synthesis and biochemical research. It is particularly sought after by pharmaceutical R&D teams and fine chemical manufacturers for developing novel compounds and studying metabolic pathways.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for metabolic and neurological targets.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies to investigate the ornithine metabolic pathway and related biochemical processes.
• Peptide Synthesis: Employed as a modified amino acid residue in the synthesis of specialized peptides and peptidomimetics for drug discovery.
• Nutritional Science Studies: Utilized in research models to study amino acid metabolism, supplementation effects, and related physiological functions.
• Reference Standard: Acts as a high-purity analytical standard for quality control and method development in pharmaceutical and research laboratories.
• Cosmetic Ingredient R&D: Investigated for potential applications in advanced skincare formulations targeting cellular repair and anti-aging.

Quality Control

Our δ-n-Hydroxyornithine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling via techniques such as HPLC, chiral analysis, and NMR to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

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 hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
