Import Benzocyclobutene-4-Boronic Acid — Buy in Bulk from Supplier in China

Benzocyclobutene-4-boronic acid (CAS 195730-31-5) is a boronic acid derivative built on the bicyclic benzocyclobutene ring, carrying the boric acid moiety at the 4-position. Its molecular formula C8H7BO2 gives a formula weight of 146.95 g/mol, and the compound is offered at a purity of 98.0% by this Chinese supplier. The boronic acid functional group makes it a versatile reagent for Suzuki-Miyaura cross-coupling and related C-C bond forming reactions. Shanghai MOF Chemical Tech Limited lists it as a bulk chemical for industrial and research use, with supply originating from their facility in Shanghai Pudong.

The bicyclic benzocyclobutene core provides a strained four-membered ring fused to a benzene ring, a structure that introduces unique reactivity and steric constraints in polymer and materials synthesis. Boronic acids of this class typically exhibit moderate air stability but benefit from dry, inert-atmosphere storage to prevent protodeboronation or oxidation. Standard handling requires protection from moisture and light, with typical storage at 2-8°C under nitrogen. The 98% purity grade is standard for commercial bulk supply in fine chemical markets, suitable for scale-up rather than analytical reference use. Impurity profiles typically include residual boronic acid anhydride and trace metallic content from the synthesis.

Primary applications span organic electronics, advanced polymer synthesis, and pharmaceutical intermediate manufacture. The compound serves as a monomer or comonomer in thermally polymerisable systems, exploiting ring-opening of the cyclobutene at elevated temperatures. Buyers include specialty chemical manufacturers, OLED materials producers, and contract research organisations running multi-step syntheses. For trade terms, prospective importers should confirm packaging format (typical: fluorinated polyethylene bottles or stainless steel drums), available batch sizes, and whether COA and MSDS documentation is provided in English. The supplier's Harbor trust tier and 0% response rate suggest direct communication before committing to trial orders.

Shanghai MOF Chemical Tech Limited operates from 5F, Building 10, 88 Darwin Road in Shanghai's Pudong district (postal code 201203), a location within one of China's principal chemical and pharmaceutical industry clusters. The supplier carries an Imported tier designation and Harbor trust classification. The response rate stands at 0.00% with zero average response hours recorded, which signals that direct outreach is essential before reliance on any listed capability. The company name suggests specialisation in metal-organic frameworks or related specialty chemicals, though buyers should verify actual production versus trading scope.

The listing positions the supplier as offering benzocyclobutene-4-boronic acid in bulk quantities, but no verified production capacity, ISO certification, or quality management system is confirmed in the available data. There is no stated workforce size, annual revenue, year of establishment, or named clientele. Prospective buyers should request a company profile, business licence, and batch-specific certificate of analysis before advancing to sample orders. Given the technical nature of boronic acid handling, it is also worth confirming whether the supplier maintains in-house analytical capability (HPLC, NMR, GC-MS) or relies on third-party testing.
