In the rapidly evolving landscape of organic electronics, the demand for high-performance intermediates continues to surge. Specifically, 9-phenylcarbazole-3-boronic acid has established itself as a critical building block for the synthesis of advanced host materials and emitters. As the industry shifts towards more efficient organic light-emitting diodes (OLEDs), securing a reliable supply chain for this OLED material precursor is essential for downstream manufacturers. NINGBO INNO PHARMCHEM CO.,LTD. provides direct factory supply, ensuring that chemical processors receive material that meets rigorous technical specifications without the markup associated with secondary distributors.
This compound, often referred to technically as (9-phenylcarbazol-3-yl)boronic acid, serves as a vital Suzuki coupling reagent in the construction of complex conjugated systems. The structural integrity of the carbazole unit combined with the reactive boronic acid moiety allows for precise carbon-carbon bond formation. For process chemists, the focus is not merely on availability but on industrial purity. Trace halides or excessive homocoupling byproducts can significantly diminish the efficiency of the final electronic device. Therefore, our manufacturing process emphasizes rigorous purification steps, including recrystallization and column chromatography, to ensure the removal of catalyst residues and unreacted starting materials.
Technical Specifications and Synthesis Route
Understanding the physicochemical properties of the material is crucial for safe handling and optimal reaction performance. The molecular formula is C18H14BNO2, with a formula weight of 287.13 g/mol. The compound typically presents as a solid off-white to light yellow powder. Stability is a key concern; the boronic acid group is susceptible to protodeboronation under harsh acidic conditions or prolonged exposure to moisture. Consequently, storage protocols recommend keeping the container tightly closed under an inert atmosphere, such as nitrogen, and maintaining temperatures between 2°C and 8°C to preserve potency over extended periods.
From a synthesis perspective, the production route generally involves the lithiation of 3-bromo-9-phenylcarbazole followed by quenching with a borate ester, or alternatively, direct borylation using bis(pinacolato)diboron followed by hydrolysis. Our facility optimizes this synthesis route to maximize yield while minimizing waste generation. The final product is analyzed using HPLC and NMR to confirm identity and purity levels exceeding standard market offerings. Below is a summary of the key technical parameters maintained during production:
| Parameter | Specification | Test Method |
|---|---|---|
| Chemical Name | 9-Phenyl-9H-Carbazol-3-Ylboronic Acid | NMR |
| CAS Number | 854952-58-2 | - |
| Purity (HPLC) | ≥ 99.0% | Area Normalization |
| Moisture Content | ≤ 0.5% | Karl Fischer |
| Heavy Metals | ≤ 10 ppm | ICP-MS |

Volume-Based Pricing Tiers for 25 kg Drum Orders
Procurement strategies for fine chemicals differ significantly from laboratory-scale purchasing. For industrial clients, the bulk price is determined by volume commitments and contract duration. We structure our pricing tiers to reward long-term partnerships and larger order quantities. Standard packaging for bulk orders typically involves 25 kg fiber drums with double polyethylene liners to ensure moisture protection during transit.
Orders exceeding 100 kg qualify for preferred pricing brackets, while annual supply agreements for metric ton quantities offer the most competitive rates. This tiered approach allows production managers to forecast costs accurately. Unlike spot-market purchases where volatility is common, contract manufacturing with NINGBO INNO PHARMCHEM CO.,LTD. locks in pricing stability, protecting your margin against raw material fluctuations. Clients are encouraged to discuss their projected annual consumption during the initial inquiry to receive a tailored quotation that reflects their specific scale of operation.
Global Logistics and Incoterms for Bulk Chemical Procurement
Efficient logistics are as critical as chemical quality. When sourcing high-purity intermediates from a verified global manufacturer, buyers should expect flexibility in shipping terms to accommodate their internal supply chain requirements. We support standard Incoterms including FOB, CIF, and DDP, depending on the destination and regulatory landscape.
Given the sensitivity of boronic acids to moisture and heat, all shipments are packed with desiccants and temperature-controlled logistics are available upon request for sensitive regions. Documentation is comprehensive, including the Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and Statement of Origin. For hazardous classifications, the product falls under specific H-statements (H315, H319, H335), requiring appropriate labeling and handling during transport. Our logistics team coordinates with certified freight forwarders to ensure compliance with international maritime and air freight regulations, minimizing customs clearance delays.
Requesting Custom Quotes for Industrial Scale Production
Every production facility has unique requirements regarding particle size, packaging, or specific impurity profiles. We offer custom synthesis services to adapt the standard manufacturing process to client specifications. To request a custom quote, potential partners should provide details on their target purity, required volume, and desired delivery timeline. Our technical sales team will evaluate the feasibility and provide a lead time estimate.
Transparency is central to our commercial engagement. We provide sample batches for qualification purposes prior to full-scale production runs. This allows your quality control department to validate the material in your specific process environment. By establishing a direct line of communication with the factory, you eliminate intermediaries, reducing lead times and ensuring that any technical queries regarding the carbazole boronic acid are answered by chemists familiar with the production process.
