Description

D-Raffinose Pentahydrate

D-Raffinose Pentahydrate is a high-purity, naturally derived Trisaccharide used in pharmaceutical, biotechnological, and nutritional applications as a stabilizer, cryoprotectant, and carbohydrate excipient. Known for its low reducing activity and excellent compatibility with proteins and biologics, it is widely incorporated into lyophilized and parenteral formulations. D-Raffinose Pentahydrate is

• A pharmaceutical-grade non-reducing trisaccharide with five molecules of water of hydration
• Used as a cryoprotectant, lyoprotectant, and stabilizer in biologics and vaccines
• Suitable for parenteral formulations, lyophilization, and diagnostic reagents
• Compatible with proteins, peptides, nucleic acids, and live-virus formulations
• Is manufactured under Good Manufacturing Practice (GMP) conditions
• Supplied with complete regulatory documentation including Certificate of Analysis (CoA) and supporting technical data

Chemically composed of Galactose, Glucose and Fructose units (α-D-galactopyranosyl-(1→6)-α-D-glucopyranosyl-(1↔2)-β-D-fructofuranose), D-Raffinose Pentahydrate is non-reducing and less reactive than reducing sugars, making it ideal for stabilizing sensitive biopharmaceuticals.

In pharmaceutical and biotechnological applications, D-Raffinose Pentahydrate is used in:

• Lyophilized formulations as a stabilizer and bulking agent for proteins and vaccines
• Cryopreservation media for cell lines, viruses, and stem cells
• Parenteral formulations and injectables to improve solubility and isotonicity
• Diagnostic kits and reagents where carbohydrate stability is essential
• Nutritional applications as a non-reducing sugar and osmotic agent

Its ability to form hydrogen bonds and protect tertiary protein structure during freezing and drying makes it especially valuable in high-value biologic formulations. Raffinose also helps maintain isotonicity and osmotic balance in parenteral products.

CarboMer supplies D-Raffinose Pentahydrate with tight control over moisture content, microbial purity, endotoxins, and heavy metals to ensure compatibility with sensitive therapeutic agents.

The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in research, pilot, and commercial-scale quantities. Minimum order quantities (MOQ), lead times, and technical documentation including CoA and SDS are provided upon request.

Each batch is tested for identity, assay, water content (Karl Fischer), pH, heavy metals, endotoxins, and microbial limits. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation accompany every shipment.

As with all CarboMer specialty carbohydrates and stabilizers, D-Raffinose Pentahydrate is supported by formulation guidance, regulatory expertise, and reliable global supply to help you develop stable, effective, and high-performance biologic products.
