Import Beta-D-Ribofuranose 1, 2, 3, 5-Tetraacetate — Buy in wholesale FOB from Supplier in China

Beta-D-ribofuranose 1,2,3,5-tetraacetate (molecular formula C13H18O10) is a fully acetylated ribose derivative that serves as a standard glycosyl donor and protected carbohydrate building block in nucleoside and nucleotide chemistry. The compound consists of a ribofuranose core with acetate esters at all four hydroxyl positions, rendering it stable to mild basic conditions while allowing selective deprotection under controlled nucleophilic or enzymatic cleavage. Relianchem Corporation supplies this material as a high-purity organic chemical intermediate targeted at pharmaceutical API synthesis, antiviral drug manufacturing, and biochemical research. The fully acetylated structure differentiates it from partially protected analogues by offering uniform reactivity profiles and simplified purification in multi-step syntheses.

In industrial practice, 1,2,3,5-tetra-O-acetyl-beta-D-ribofuranose is valued for its role in constructing the ribose moiety of ribavirin and related antiviral nucleoside analogues. The material is typically manufactured through peracetylation of D-ribose under acidic catalysis with acetic anhydride, followed by crystallisation to achieve the characteristic anomeric purity required for subsequent glycosylation. Standard quality parameters for this grade include greater than or equal to 98% purity by HPLC, specific rotation near -25 degrees (c=1, chloroform) for the beta-anomer, and low free sugar content. Typical residual solvents are controlled to ICH Q3C limits, with particular attention to acetic acid and acetic anhydride traces. The crystalline solid is moderately hygroscopic and should be stored in a tightly closed container with desiccant to prevent hydrolysis of the acetate groups.

Buyers span custom synthesis organisations, generic API producers, biotechnology companies, and academic laboratories engaged in medicinal chemistry. Relianchem Corporation indicates bulk packaging for industrial and laboratory use, though exact pack sizes are not stated on the listing. The company notes global trade in this specialty fine chemical, reflecting demand from pharmaceutical manufacturing sectors. Importers should confirm with Relianchem Corporation the available packaging formats (typical range 1 kg to 25 kg), whether the material is offered as the anomerically pure beta-form or as a mixture, and what documentation accompanies each shipment. Given the zero percent response rate recorded, direct outreach through the Xiamen address or alternative channels may be necessary to obtain quotations and confirm lead times.

Relianchem Corporation is based at No. 885 Xiahe Road, Siming District, Xiamen City, Fujian Province 361010, China. The supplier holds a 'harbor' trust tier on the platform, with a response rate of 0.00 percent and zero average response hours recorded. These figures indicate limited or no engagement with enquiries through the platform channel. No information is provided about the year of establishment, number of employees, annual turnover, or production versus trading model. The Xiamen location is a known hub for chemical and pharmaceutical trading companies, which may operate as manufacturers, distributors, or hybrid entities.

The listing for Relianchem Corporation includes a detailed product description emphasising pharmaceutical and biochemical applications, but does not cite GMP certification, ISO accreditation, or specific manufacturing facility details. No client references, export volumes, or country-specific registrations are mentioned. Buyers should independently verify the company's business registration through the Fujian Administration for Market Regulation, request proof of manufacturing or sourcing agreements for this specific intermediate, and ask for reference customers in comparable markets. The absence of response activity on the platform suggests that alternative contact methods (direct email, telephone, or the Xiamen address) may yield faster communication than platform messaging.
