Description

n-Hexyl Aspartic Acid is a specialty amino acid derivative where the hexyl group modifies the properties of the parent L-aspartic acid. This structural modification enhances its lipophilicity, making it a valuable building block for synthesizing novel surfactants, peptides, and functional polymers. It is particularly relevant for R&D and production in the personal care, pharmaceutical, and specialty chemical industries seeking to tailor solubility and biological activity.

Application

• Surfactant & Detergent Intermediate: Serves as a key precursor for synthesizing novel amino acid-based surfactants with mild and biodegradable properties for cosmetic and cleaning formulations.
• Pharmaceutical Building Block: Used in the research and development of peptide-based drugs and prodrugs, where the hexyl chain can influence membrane permeability and pharmacokinetics.
• Personal Care Ingredients: Employed in the creation of specialty conditioning agents, emulsifiers, and skin-compatible active ingredients for high-end skincare and haircare products.
• Polymer Modification: Acts as a monomer or modifier for producing functional polymers with tailored properties for biomedical or industrial applications.
• Cosmetic Actives Carrier: Utilized to enhance the delivery and stability of active compounds in cosmetic formulations due to its amphiphilic nature.
• Chemical Synthesis Intermediate: Functions as a versatile chiral synthon in organic synthesis for creating complex molecules in agrochemical and material science research.

Quality Control

Our n-Hexyl Aspartic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, enantiomeric purity, and impurity profiles are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 moisture absorption, which may affect product stability.
