o-Phenylbenzoic acid
Overview
o-Phenylbenzoic acid, also known as 2-phenylbenzoic acid, is an organic compound commonly used as an intermediate in chemical synthesis. It is a white to off-white crystalline powder with a molecular weight of 198.22 g/mol. This compound is valued in industries such as pharmaceuticals and dyes for its role in producing more complex molecules. Its synthesis typically involves the oxidation of o-phenyltoluene or similar precursors. The compound is stable under normal conditions but requires careful handling to avoid decomposition or contamination. Due to its versatile applications, it is a sought-after chemical in B2B markets.
Physical and Chemical Properties
o-Phenylbenzoic acid is characterized by its white crystalline appearance and a melting point of approximately 122-124°C. It is soluble in organic solvents like ethanol and acetone but only slightly soluble in water. These properties make it suitable for use in organic synthesis where solubility in non-polar solvents is advantageous. The compound is stable under standard conditions but may react with strong oxidizing agents, leading to decomposition. Its molecular structure, featuring a carboxyl group attached to a biphenyl framework, contributes to its reactivity and utility in various chemical reactions.
Main Applications
o-Phenylbenzoic acid is primarily used as an intermediate in the synthesis of pharmaceuticals, where it serves as a building block for more complex molecules. It is also employed in the production of dyes and pigments, contributing to vibrant and stable color formulations. In addition, this compound finds use in the manufacture of fine chemicals, including specialty polymers and agrochemicals. Its versatility and reactivity make it a valuable component in industrial chemistry, particularly in processes requiring precise molecular control.
Safety and Storage
When handling o-phenylbenzoic acid, it is essential to avoid inhalation or direct contact with skin and eyes. Personal protective equipment (PPE), such as gloves and goggles, should be worn to minimize exposure. The compound should be stored in a cool, dry place, away from direct sunlight and moisture, to maintain its stability. In case of accidental exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Proper disposal methods should be followed to prevent environmental contamination, adhering to local regulations for chemical waste.
B2B Procurement Guide
When procuring o-phenylbenzoic acid, buyers should verify the purity and CAS number (117-38-2) to ensure they receive the correct compound. It is advisable to source from reputable suppliers with certifications such as ISO or GMP, as these indicate adherence to quality standards. Price ranges typically fall between $50-$100 per kilogram, depending on purity and order quantity. Buyers should also request batch consistency reports and material safety data sheets (MSDS) to ensure compliance with safety and regulatory requirements. Bulk purchases may offer cost savings, but storage conditions must be carefully managed.
