Import 5-Bromo-2s-Deoxyuridine — Buy in Bulk from Supplier in China

5-Bromo-2'-deoxyuridine (BrdU, CAS 59-14-3, molecular formula C9H11BrN2O5, molecular weight 307.10 g/mol) is a halogenated pyrimidine nucleoside analogue supplied by Nanjing Search Bio Co., Ltd from their facility in the Nanjing Economic Development Zone Pharmaceutical Industry Garden, Jiangsu Province, China. The compound is presented as a white to off-white powder for biochemical and molecular biology applications, particularly DNA synthesis studies and cellular proliferation assays. As a thymidine analogue, BrdU incorporates into replicating DNA and serves as a standard tool for detecting cell cycle progression, making it fundamental to oncology research, developmental biology, and neurogenesis studies. Nanjing Search Bio positions this material for export to research laboratories, biotech firms, and universities globally.

The molecular structure comprises deoxyribose sugar linked to a 5-bromouracil base through an N-glycosidic bond, with the 5-bromo substitution conferring immunogenic distinction from thymidine that enables antibody-based detection. Purity specifications for research-grade BrdU typically require ≥98% HPLC purity with limited related substances including thymidine, 2'-deoxyuridine, and 6-alkyluracil derivatives. The compound is hygroscopic and light-sensitive, standard for nucleoside analogues, requiring storage at -20°C under desiccated conditions. Nanjing Search Bio's location in a designated pharmaceutical industry zone suggests access to regulated manufacturing infrastructure, though buyers should confirm whether production occurs in the stated facility or through contracted manufacturers. The supplier's Harbor trust tier with zero platform response rate means direct technical engagement is essential before purchase commitment.

Primary applications include in vivo and in vitro cell proliferation assays (flow cytometry, immunohistochemistry, ELISA), neurogenesis tracking in rodent models, and antiviral research where BrdU serves as a reference compound. Buyers include academic core facilities, pharmaceutical discovery groups, and diagnostics developers. For procurement, confirm with Nanjing Search Bio whether their offering is catalogued as cell-culture grade (endotoxin-tested, sterile-filtered) or standard research grade, as this determines suitability for live-cell applications. Certificate of analysis content, stability data, and whether the lot is manufactured under ISO 9001 or GMP-for-reagents guidelines should be requested directly. The supplier's imported tier designation indicates they engage in cross-border trade, but import documentation capabilities for your specific destination country require verification.

Nanjing Search Bio Co., Ltd is located in Building 5 of the Nanjing Economic Development Zone Pharmaceutical Industry Garden, Nanjing 210038, Jiangsu Province, China. This address places the supplier within a government-designated zone intended for pharmaceutical and biotechnology enterprises, which may provide infrastructure advantages for regulated material handling, though the specific facility ownership and manufacturing versus distribution role should be confirmed directly. The supplier holds both Imported and Harbor trust tier designations, indicating some level of cross-border trade experience combined with baseline platform verification. The zero percent response rate and zero recorded average response hours suggest limited active engagement through platform messaging, making direct outreach via telephone or email essential for technical discussions and order negotiation.

The available profile data does not disclose company founding date, employee count, annual turnover, product portfolio breadth, or specific quality management system certifications. The listing's reference to ISO and CE compliance in the source description should be verified by requesting current certificates with scope and accreditation body details, as these claims are not independently confirmed in the extracted data. Nanjing Search Bio's focus on biochemical reagents, as inferred from their product offering, implies specialization in research-use materials rather than GMP-grade pharmaceutical intermediates, but this distinction must be clarified for applications beyond basic research. Buyers should request a company profile, manufacturing license from Jiangsu drug regulatory authorities, and evidence of facility inspection history before committing to volume procurement.
