D-Mannose (CAS Number: 3458-28-4, Molecular Formula: C6H12O6, Molar Mass: 180.16 g/mol), also systematically recognized in pharmaceutical and biomanufacturing domains as E-D-Mannose or D-mannopyranose, is a naturally occurring C-2 epimer of D-glucose. Over the past decade, D-Mannose has transitioned from a niche biochemical research substrate into a critical global commodity serving the pharmaceutical, nutraceutical, cosmeceutical, and veterinary healthcare industries. Driven by a global paradigm shift toward non-antibiotic anti-infective agents and targeted glycobiology therapeutics, the global demand for high-purity D-Mannose has experienced unprecedented growth, registering a compound annual growth rate (CAGR) exceeding 8.5%.
China has emerged as the premier manufacturing epicentre for global D-Mannose, hosting state-of-the-art biomanufacturing hubs capable of delivering multi-thousand-ton annual volumes. Strategic investments in enzymatic conversion technology, high-efficiency continuous chromatography, and green chemistry principles have positioned Chinese suppliers as indispensable partners for global pharmaceutical companies and dietary supplement brands across Europe, North America, and the Asia-Pacific region.
Chemical Name: D-Mannose / E-D-Mannose | CAS Number: 3458-28-4 | EINECS No.: 222-392-4 | Purity Standard: ≥99.0% (HPLC Assay) | Physical State: White Crystalline Powder | Solubility: Highly Soluble in Water (2500 g/L at 20°C), Slightly Soluble in Ethanol | Melting Point: 126°C to 133°C.
The commercial manufacturing of D-Mannose in China has evolved through two distinct technological paradigms: classical chemical/acid hydrolysis and advanced multienzyme biocatalysis. Leading Chinese manufacturers, including technical innovators associated with JIMPOCHEM, have largely transitioned to third-generation enzymatic technologies to eliminate toxic chemical byproducts, improve atom economy, and achieve strict USP/EP compliance.
Utilizing immobilized D-fructose 3-epimerase (DPEase) and D-lyxose isomerase derived from genetically optimized, non-GMO microbial strains (e.g., Bacillus subtilis or Escherichia coli expression hosts). Food-grade D-glucose or D-fructose serves as the initial renewable feedstock.
Extraction from natural plant polysaccharides, specifically plant galactomannans such as guar gum, spent coffee grounds, or ivory nut palm. Acid-catalyzed cleavage breaks glycosidic bonds to yield D-mannose alongside structural impurities.

| Purity (HPLC) | ≥ 99.5% (Ultra-Pure) | 97.0% - 98.5% |
| Heavy Metals (as Pb) | < 5 ppm | < 10 - 20 ppm |
| Microbial Endotoxins | < 0.25 EU/mL (Injectable Grade Available) | Requires Extensive Carbon Depyrogenation |
| Impurity Profile | Zero acid degradants; Minimal D-Glucose residue | Trace oligosaccharides, furfural derivatives |
| Scalability & Sustainability | High continuous output, eco-friendly, carbon-efficient | Moderate, constrained by agricultural supply chains |
Due to its unique structural stereochemistry, D-Mannose undergoes distinct metabolic routing compared to glucose. It is absorbed rapidly into the bloodstream, passes largely un-metabolized through the upper gastrointestinal tract, and is excreted via the kidneys into the urinary tract. This bio-behavior underpins its broad application across diverse industrial sectors:
D-Mannose serves as the gold-standard non-antibiotic intervention for Urinary Tract Infections (UTIs), primarily caused by Uropathogenic Escherichia coli (UPEC). The FimH lectin protein located on the pili of UPEC selectively binds to D-Mannose monomers rather than the urothelial cell surface glycocalyx. This competitive inhibition prevents bacterial adhesion, allowing pathobionts to be naturally flushed out during urination.
In cell culture and biopharmaceutical manufacturing, high-purity D-Mannose is a vital precursor in N-glycosylation pathways. Recent oncological studies highlight D-Mannose’s capacity to interfere with cellular glucose uptake in specific tumor lineages, impairing glycolytic flux and enhancing sensitivity to conventional chemotherapeutic regimens without systemic toxicity.
Incorporated as a prebiotic conditioning agent and humectant in high-end dermatological skincare. D-Mannose supports beneficial skin microflora (such as Staphylococcus epidermidis) while inhibiting opportunistic pathogens, improving skin barrier hydration, reducing transepidermal water loss (TEWL), and calming inflammatory skin states.
As global regulations phase out prophylactic antibiotics in livestock production, D-Mannose is extensively used as a functional feed additive. It reduces pathogenic colonization in swine and poultry GI tracts, improving gut mucosal integrity, nutrient absorption efficiency, and overall herd immunity.
Utilized as a chiral pool starting material in organic synthesis for complex carbohydrate-based pharmaceuticals, chiral ligands, and active pharmaceutical ingredients (APIs) requiring specific stereochemical configurations at the C-2 and C-3 positions.
Formulated alongside proanthocyanidins (PACs) from Cranberry extracts, Probiotic strains (Lactobacillus rhamnosus), and D-Chiro-Inositol to create multi-target functional stick packs, effervescent tablets, and hard capsules designed for urinary health and immune support.
In international chemical and pharmaceutical procurement, supply chain security depends on stringent quality management systems. Leading Chinese manufacturers enforce total quality control (TQC) frameworks from raw material intake to final packaging.
Every batch undergoes High-Performance Liquid Chromatography (HPLC) for quantification, Gas Chromatography (GC) for residual solvent verification, and ICP-MS for ultra-trace heavy metal detection. Optical rotation, loss on drying (LOD), and ignition residue are tested in accordance with USP/EP monographs.
Facility compliance includes ISO 9001:2015 Quality Management Systems, ISO 22000 / FSSC 22000 Food Safety Systems, cGMP-compliant cleanrooms (Class 100,000 / ISO Class 8), along with Kosher, Halal, and Non-GMO Project Verification.
Full digital batch record system linking raw material lots, bioreactor operating parameters, filtration logs, and packaging lines. Global shipping options include climate-controlled containerization with real-time temperature and humidity tracking.
