Import Borane-Triethylamine Complex 1722-26-5 — Buy in wholesale FOB from Supplier in China

Borane-triethylamine complex (CAS 1722-26-5) is a liquid coordination compound in which a triethylamine ligand stabilises the borane moiety, yielding a colourless to pale yellow oil with the formula C6H18BN and a molecular weight of 115.04 g/mol. This complex serves as a milder and more selective reducing agent than borane-tetrahydrofuran adducts, with particular utility in the reduction of imines, enamines and certain functionalised ketones where over-reduction must be avoided. The compound remains liquid across a broad temperature range, with a boiling point of approximately 68 degrees Celsius at 0.5 mmHg, and it decomposes exothermically in the presence of protic solvents or atmospheric moisture. Its commercial formulations typically assay at 95% purity or higher, with the active borane content standardised for stoichiometric consistency in scale-up operations.

The manufacturing process for borane-triethylamine complex typically involves direct combination of diborane or borane precursors with triethylamine under anhydrous conditions, followed by distillation to remove unreacted amine and higher-boiling oligomeric by-products. Standard quality parameters include a density of 0.74-0.78 g/cm3 at 25 degrees Celsius, a refractive index in the range of 1.44-1.46, and a water content below 0.1% by Karl Fischer titration. The product is supplied with a nitrogen or argon blanket in containers ranging from 100 millilitre bottles to 200 litre drums, depending on the supplier's standard offering and the buyer's volume requirements. Long-term storage stability is enhanced by the triethylamine ligand, which provides greater thermal stability than ether-stabilised borane complexes, though oxidative degradation remains a concern if the inert atmosphere is compromised.

Industrial applications span pharmaceutical intermediate synthesis, agrochemical active ingredient production, and polymer research where controlled reduction chemistry is required. The complex is especially valued in processes where the volatility and flammability of borane-dimethyl sulfide or borane-tetrahydrofuran present unacceptable safety profiles. Buyers in North America and Europe source this material from Chinese manufacturers to access cost advantages, though they must navigate REACH or TSCA registration requirements depending on the import jurisdiction. When engaging Zhengzhou Kingsfine Chemical Co., Ltd., prospective customers should focus initial discussions on the supplier's batch size capability, analytical methodology for active content verification, and track record with air-sensitive liquid chemical exports, as these factors determine whether the supplier can reliably support ongoing manufacturing campaigns.

Zhengzhou Kingsfine Chemical Co., Ltd. maintains its registered address on Chenguan Road within the Hi-Tech Industrial Development Zone of Zhengzhou, Henan Province, a central Chinese location with established chemical logistics infrastructure. The supplier's profile indicates an 'imported' tier and 'harbor' trust classification, which represents entry-level verification rather than comprehensive third-party accreditation. The recorded 0.00% response rate and zero average response hours signal that platform-mediated communication may not be monitored actively, and buyers should expect to initiate contact through direct channels. No data is available on the company's founding date, employee count, annual revenue, or number of export destinations served.

The supplier lists borane-triethylamine complex among its product offerings but does not disclose details of its manufacturing footprint, such as whether production occurs in-house or through toll arrangements, or whether the facility operates under cGMP, ISO 9001, or other recognised quality management standards. The absence of stated certifications, client references, or case studies in the available profile means buyers must conduct independent due diligence. Prospective customers should request a facilities questionnaire, recent audit reports if available, and evidence of hazardous materials handling training for shipping personnel before advancing to commercial discussions.
