Description

(4-(1-(Cyclopropylamino)Ethyl)Phenyl)Boronic Acid Hydrochloride is a high-value, organoboron-based chemical building block, specifically a boronic acid derivative, essential for modern synthetic chemistry. Its core value lies in its role as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. This compound is critically needed by pharmaceutical R&D teams, agrochemical manufacturers, and advanced material scientists for the development of novel active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders, oncology, and infectious diseases.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific, complex aryl-aryl linkages.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of advanced polymers, organic electronic materials, and metal-organic frameworks (MOFs).
• Chemical Biology & Probe Development: Employed in creating molecular probes and sensors that utilize boronic acid's affinity for diols, useful in carbohydrate sensing and diagnostics.
• Catalyst Ligand Precursor: Acts as a starting material for synthesizing specialized ligands used in homogeneous catalysis.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for bespoke synthesis projects requiring specific boronic acid derivatives.

Quality Control

Our (4-(1-(Cyclopropylamino)Ethyl)Phenyl)Boronic Acid Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high purity and consistent performance for critical coupling reactions. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage at 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
