For procurement managers and R&D scientists in the pharmaceutical and advanced materials sectors, the efficient and reliable sourcing of key chemical intermediates is critical to project success. 4-Pentylbenzeneboronic acid (CAS 121219-12-3) is one such intermediate, highly sought after for its role in sophisticated synthesis pathways. This guide aims to provide insights into procuring this valuable compound, focusing on what buyers should look for from manufacturers and suppliers.

Understanding the Specifications of 4-Pentylbenzeneboronic Acid

When evaluating suppliers, buyers should pay close attention to the following technical specifications:

• Product Name and CAS Number: Ensure accurate identification, confirming it is indeed 4-pentylbenzeneboronic acid with CAS number 121219-12-3. Other names like 4-Amylbenzeneboronic acid or 4-n-Pentylbenzeneboronic acid may be listed, but the CAS number is the definitive identifier.
• Appearance: Typically, this compound is supplied as an off-white powder. Variations in color could indicate differing purity levels or minor impurities.
• Assay/Purity: This is arguably the most critical specification. For demanding applications like pharmaceutical synthesis and OLED materials, a high assay, such as ≥98.0%, is essential. Lower purities may suffice for less sensitive research but could compromise downstream processes.
• Water Content: A low water content, ideally ≤0.50%, is important for stability and for ensuring accurate reaction stoichiometry in sensitive chemical transformations.
• Molecular Formula and Weight: C11H17BO2 and 192.06200 respectively, these confirm the chemical identity.

Key Application Areas Driving Demand

The primary drivers for purchasing 4-pentylbenzeneboronic acid are its applications as:

• Pharmaceutical Intermediates: It acts as a crucial building block in the synthesis of Active Pharmaceutical Ingredients (APIs) through various coupling reactions.
• OLED Intermediates: Its integration into organic molecules used in OLED displays and lighting contributes to improved electronic and optical properties.

Understanding these applications helps buyers articulate their needs and assess the suitability of a supplier's product.

Finding a Reliable Supplier and Manufacturer

When you need to buy 4-pentylbenzeneboronic acid, consider these points for selecting a supplier:

• Manufacturing Capabilities: Does the supplier manufacture the product in-house or source it from a reliable primary manufacturer? Understanding the origin ensures quality control. Manufacturers in China often offer competitive pricing and high production volumes.
• Quality Control Processes: Inquire about their quality assurance procedures, the availability of Certificates of Analysis (COA) for each batch, and their adherence to industry standards.
• Supply Chain Reliability: Look for suppliers who can demonstrate consistent stock levels and efficient logistics to ensure timely delivery, whether for R&D samples or bulk orders.
• Customer Service and Technical Support: A responsive supplier who can answer technical queries and assist with logistical challenges is invaluable.
• Pricing and Bulk Discounts: Obtain quotes and compare pricing structures, especially for larger quantities. Buying directly from a manufacturer can often yield better prices.
