4-Aminophenylboronic acid pinacol ester (CAS Number: 214360-73-3) is a boronic acid derivative valued for its role in carbon–carbon bond-forming reactions featuring a Benzene ring. ChemContract Research supplies this moderate-complexity compound in high purity from our Huntington Beach, California facility, ensuring consistent quality and reliable domestic delivery throughout the United States.
The boron atom in this compound enables transmetalation with palladium catalysts, making it a cornerstone reagent for Suzuki coupling — one of the most widely used reactions in pharmaceutical process chemistry. Amines are among the most prevalent functional groups in drug molecules — over 80% of small-molecule pharmaceuticals contain at least one amine moiety. Ester hydrolysis by cellular esterases is the most commonly exploited prodrug activation mechanism — enabling drugs that cannot cross biological membranes as free acids.
Primary applications include suzuki–miyaura cross-coupling for biaryl and heterobiaryl synthesis and buchwald–hartwig amination for aryl c–n bond construction. This compound serves researchers and manufacturers across the pharmaceutical, medicinal chemistry, diagnostics sectors. Whether you require 4-Aminophenylboronic acid pinacol ester for early-stage research, process development, or commercial-scale production, ChemContract Research offers flexible ordering from milligram to multi-kilogram quantities with custom synthesis options and full batch documentation including Certificates of Analysis (CoA) and Safety Data Sheets.

Detailed specifications for this boronic acid / boronate ester, including purity, molecular weight, and analytical data are available upon request. Every batch from ChemContract Research includes:
Boronic acids are generally air-stable but some may be moisture-sensitive and undergo protodeboronation. Handle with gloves and safety glasses. Amines may have strong odors and can be corrosive to skin. Handle under adequate ventilation with chemical-resistant gloves and eye protection. Some esters are volatile and flammable. Handle in a well-ventilated area. Keep away from ignition sources.
Store in a tightly sealed container at room temperature under dry conditions. Protect from prolonged moisture exposure. Store in a cool, well-ventilated area away from acids and oxidizing agents. Keep containers tightly sealed as many amines are hygroscopic. Store at room temperature in a tightly sealed container away from heat and open flame.
