In the realm of fine chemicals and intermediates, precise specifications are paramount. 3-Fluorophenylboronic Acid (CAS 768-35-4) is no exception, with its technical attributes dictating its suitability for demanding applications in pharmaceutical synthesis, material science, and beyond. Understanding these specifications ensures that users can confidently employ this valuable reagent in their processes.

A key technical detail is its appearance: 3-Fluorophenylboronic Acid is typically supplied as a white crystalline powder. This physical state is indicative of its purity and ease of handling. Chemically, its purity is usually specified at a minimum of 98% as determined by High-Performance Liquid Chromatography (HPLC). This high level of purity is critical for avoiding side reactions and ensuring the desired outcome in sensitive Suzuki-Miyaura coupling reactions, where even minor impurities can compromise yield and product quality.

The melting point of 3-Fluorophenylboronic Acid, generally falling within the range of 158-162°C, serves as another important identifier and purity indicator. Its solubility profile, being soluble in tetrahydrofuran (THF) and dimethylformamide (DMF) and only slightly soluble in water, guides its application in various solvent systems. Storage recommendations, typically at 2-8°C in an airtight container under an inert gas, are designed to maintain its stability and shelf life of 24 months. These well-defined properties, readily available from suppliers like NINGBO INNO PHARMCHEM CO.,LTD., underscore the compound's reliability as a high-quality chemical intermediate.
