Description

Chitoheptaose Heptahydrochloride is a defined, high-purity oligosaccharide derivative of chitosan, specifically a heptamer with a hydrochloride salt form. This compound is valued for its precise molecular structure, which enables advanced research into chitin-based biological activities and mechanisms. It serves as a critical biochemical tool for scientists and manufacturers in the pharmaceutical, nutraceutical, and agricultural biotechnology sectors, particularly for studying immune modulation, plant defense elicitors, and advanced drug delivery systems.

Application

• Biomedical Research: Used as a standardized ligand or substrate for studying chitinase enzymes, innate immune receptors (e.g., TLRs, NOD receptors), and carbohydrate-protein interactions.
• Pharmaceutical Development: Serves as a key intermediate or active pharmaceutical ingredient (API) precursor in the development of immunomodulators, anti-inflammatory agents, and vaccine adjuvants.
• Agricultural Science: Employed as a well-defined elicitor in plant pathology and crop protection research to study and enhance systemic acquired resistance (SAR) in plants.
• Cosmeceuticals: Incorporated into advanced skincare formulations for its potential bioactive properties, including moisturization and skin barrier enhancement.
• Nutraceuticals: Investigated for use in functional food and dietary supplement development aimed at gut health and immune support.
• Biomaterial Engineering: Acts as a building block for creating novel, structurally precise chitosan-based hydrogels, scaffolds, and nano-carriers for controlled release applications.
• Diagnostic Reagents: Utilized in the development of biochemical assays and diagnostic kits targeting chitin-related pathways.
• Standards & Calibration: Provides a high-purity reference standard for analytical methods such as HPLC, LC-MS, and NMR in quality control and research laboratories.

Quality Control

Our Chitoheptaose Heptahydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets stringent specifications for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical parameters such as assay purity, chloride content, and residual solvents. We support compliance with relevant guidelines for research-grade biochemicals.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive). For long-term storage, consider desiccation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
