Chemical Structure
Basic Information of Beta-D-Glucose Pentaacetate:
In the fields of modern biopharmaceutical research, polysaccharide and oligosaccharide synthesis, and premium food additives, β-D-Glucose Pentaacetate (also known as 1,2,3,4,6-Penta-O-acetyl-β-D-glucopyranose, CAS No.: 604-69-3) plays an irreplaceable role as a classic fully protected carbohydrate building block. As a direct, source-level manufacturer specializing in carbohydrate chemistry and pharmaceutical intermediates for years, we understand that downstream R&D institutions and industrial clients demand strict standards for product purity, specific optical rotation, and α/β anomer ratios during glycosylation scale-up.
Manufacturing Technical Edge and Quality Control
Conventional carbohydrate acetylation processes easily generate unpredictable α/β anomeric mixtures. Because their physical properties are highly similar, subsequent separation is difficult and costly. We have implemented several proprietary process optimizations in our large-scale production line:
- Stereospecific Condensation Control: By using specialized weak base or Lewis acid catalytic systems, we strictly regulate reaction kinetics and temperatures. This pushes the equilibrium heavily toward the thermodynamically more stable β-configuration, minimizing α-anomer formation at the source.
- Multi-Stage Recrystallization: We utilize a proprietary composite solvent recrystallization technique. This completely removes residual acetic acid and acetic anhydride from the reaction (reducing free acids to absolute minimums) while ensuring uniform crystal size. This drastically enhances the chemical stability and shelf life of the product in open air.
- Trace and Heavy Metal Mitigation: As a critical pharmaceutical intermediate, our plant strictly manages manufacturing equipment metallurgy and pipeline rinsing protocols. We restrict heavy metals like iron, lead, and arsenic to ultra-low ppm levels, meeting direct warehouse-in inspection standards for downstream pharma giants.
Product Usage:
The unique fully protected structure of β-D-Glucose Pentaacetate offers exceptional flexibility in synthesizing carbohydrate-containing molecules:
- Glycosyl Donors and Oligosaccharide Synthesis: Under Lewis acid catalysis, the anomeric acetoxy group (1-O-acetyl) acts as an excellent leaving group for synthesizing various simple or complex glycosides, oligosaccharides, and glycoconjugates. It can also be easily converted into highly reactive glycosyl halides (like acetobromo-alpha-D-glucose) or thioglycosides.
- Prodrug and Pharmaceutical Development: Research shows that specific carbohydrate-protected derivatives exhibit unique biological activities in regulating or stimulating insulin release from rat islet cells. It also serves as a vital precursor for introducing sugar moieties into various antiviral and antitumor complexes.
- Specialty Additives and Fragrance Precursors: In fine chemicals, premium daily cosmetics, and the food industry, it is widely utilized as a heat-resistant, stable flavor precursor or specialty functional additive.

Advice on Shipping
1. For products ≤50kg, we recommend using express delivery, which is usually called DDU service (discounted, convenient).
2. For products ≤500kg, we generally recommend air freight, which is usually called FOB, CFR or CIF service (fast and efficient).
3. For products >500kg, we generally recommend shipping by sea, which is usually called FOB, CFR or CIF service (economical, safe).
4. For high-value products, please choose air or express to ensure the safety of product transportation.
After-Sales Service
- After delivery, we will send a set of scanned copies of shipping documents to customers by mail, and mail the original documents in time. After the ship leaves the port, we update the shipping schedule to the customer every week and tell the customer when to arrive at the port. If customers encounter customs clearance problems, we will actively cooperate with customers to solve them. If it is an air or express delivery customer, we will provide the customer with the tracking number in time and update the information in time.
- After the customer receives the goods, we will promptly communicate with the customer about the quality and packaging of the product. Hope to get feedback from customers.
- We will provide customers with domestic market conditions and update prices in a timely manner. If conditions permit, we will also provide customers with the demand for the product in the country where they are located to help customers occupy the market.
