Import 5-(2-Bromoethyl)-2,3-Dihydrobenzofuran — Buy in wholesale FOB from Supplier in China

Zhengzhou Kingsfine Chemical Co., Ltd. offers 5-(2-bromoethyl)-2,3-dihydrobenzofuran, a heterocyclic aromatic bromide with CAS registry number 127264-14-6 and molecular formula C10H11BrO. This compound features a bromoethyl side chain at the 5-position of a 2,3-dihydrobenzofuran core, combining a partially saturated benzofuran ring system with an alkyl bromide functional group that renders it reactive toward nucleophilic substitution. The substance serves as a building block in pharmaceutical and agrochemical synthesis, where the bromoethyl moiety enables formation of amine or ether linkages in subsequent steps. The supplier describes the material as high-purity and chemically stable, though exact assay, melting point and impurity profiles are not stated in the source data and must be requested directly.

The 2,3-dihydrobenzofuran scaffold is a privileged structure in medicinal chemistry, appearing in compounds with serotonin receptor, anti-inflammatory and anticancer activities; the bromoethyl substituent at C5 provides a handle for further functionalisation via SN2 displacement. In agrochemical research, similar benzofuran intermediates feed into insecticide and fungicide programmes. Typical manufacturing routes for this class involve bromination of the corresponding alcohol or direct bromoethylation of the heterocycle under Lewis acid catalysis. Standard purity benchmarks for such intermediates in GMP-tracked projects range from 98.0 to 99.5 percent area by HPLC, with specific impurity limits for regioisomers and residual solvents (ICH Q3C classes 1-3) controlled below 0.10 percent and 5000 ppm respectively.

Buyers span custom synthesis houses, generic API manufacturers, university research groups and agrochemical discovery laboratories. The material is typically supplied in amber glass bottles or fluorinated polymer containers with nitrogen headspace to minimise oxidative degradation and moisture ingress. Zhengzhou Kingsfine Chemical indicates flexible MOQ, though no precise figure is given; buyers should confirm minimum pack sizes, tier pricing and availability of analytical data packages (COA, NMR, HPLC, MS) before purchase. The supplier is located in Zhengzhou's Hi-Tech Industrial Development Zone, suggesting access to analytical infrastructure and chemical logistics networks, but buyers should independently verify GMP or ISO registration status if audit trails are required for regulatory filings.

Zhengzhou Kingsfine Chemical Co., Ltd. is headquartered on Chenguan Road within the Hi-Tech Industrial Development Zone of Zhengzhou, Henan Province, China, postal code 450001. The supplier holds a harbour trust tier and an imported supplier tier designation, but the response rate is recorded at 0.00 percent with zero average response hours, indicating no recent engagement metrics are available. No data on year of establishment, employee count, turnover, ISO certification, GMP compliance or registered capital is present in the source material.

The company positions itself as a source of specialised chemical compounds for pharmaceutical and agrochemical synthesis, with this listing emphasising bulk supply and flexible order quantities. Buyers should conduct due diligence on quality management systems, requesting evidence of manufacturing site audits, environmental compliance permits and batch traceability protocols. The Hi-Tech Zone location implies proximity to Zhengzhou's logistics hub, but this alone does not guarantee export licence status or dangerous goods handling certification for brominated compounds.
