从China供应商批发进口5-Ethyl-2-Methylpyridine Borane — FOB条款

5-Ethyl-2-methylpyridine borane is a pyridine-borane complex used as a reducing agent and reagent in organic synthesis, particularly in pharmaceutical research and fine chemical production. Zhengzhou Kingsfine Chemical Co., Ltd. supplies this compound from Henan Province, China, describing it as a high-purity material for research and industrial applications. The borane complex derives from 5-ethyl-2-methylpyridine (a substituted pyridine also known as aldehyde collidine) complexed with borane (BH3), yielding a stable, storable source of borane reducing equivalents.

Pyridine-borane complexes are typically colourless to pale yellow liquids or low-melting solids at room temperature, depending on purity and storage temperature. The borane moiety provides hydride donation capability for selective reduction of aldehydes, ketones, imines, and related functional groups under mild conditions. Standard industry purity for such reagent-grade complexes typically ranges 95-98% with controlled borane content. The complex exhibits improved air and moisture stability compared to free borane-THF or borane-dimethylsulfide complexes, though it still requires inert atmosphere handling for long-term storage.

Primary buyers include research laboratories, contract research organisations, and pharmaceutical manufacturing facilities engaged in process development. Applications span asymmetric reduction, reductive amination, and borane transfer reactions where controlled hydride delivery is required. Zhengzhou Kingsfine Chemical Co., Ltd. mentions flexible MOQ and trade terms including FOB and CIF, though exact quantities, pricing, and lead times are not specified in the source data. Buyers should confirm these details directly with the supplier, noting the 0.00% platform response rate.

Zhengzhou Kingsfine Chemical Co., Ltd. is located on Chenguan Road in the Hi-Tech Industrial Development Zone, Zhengzhou 450001, Henan Province, China. The supplier holds a harbor trust tier with an imported tier designation, indicating the listing was created from externally sourced data rather than direct supplier verification. Platform metrics show a 0.00% response rate and zero average response hours, suggesting limited or no active engagement through this channel.

No manufacturing facility details, year of establishment, employee count, revenue, or specific certifications are provided in the source data. The company profile does not indicate whether Zhengzhou Kingsfine Chemical Co., Ltd. manufactures this pyridine-borane complex in-house or sources from another producer. Buyers should conduct independent due diligence, requesting business licence, manufacturing or distribution permits, and quality system certificates before placing orders. The Hi-Tech Zone address suggests proximity to research institutions, but this does not confirm production capability.
