Overview
Picolinic acid is an organic compound derived from pyridine, characterized by a carboxylic acid group at the 2-position. It is naturally found in some plants and microorganisms. Industrially, it is synthesized for use in pharmaceuticals, agriculture, and chemical research. Its chelating properties make it valuable in metal ion coordination, particularly in nutritional supplements and herbicides. The compound is also a precursor for various drugs and agrochemicals, highlighting its versatility in B2B applications.
Physical and Chemical Properties
Picolinic acid appears as a white to off-white crystalline powder with a melting point of 136-138 °C. It is moderately soluble in water and organic solvents like ethanol and ether. The compound exhibits weak acidic properties due to the carboxylic group. Its density is approximately 1.29 g/cm³, and it decomposes at around 290 °C. The molecular weight is 123.11 g/mol. These properties make it stable under normal storage conditions but require careful handling to avoid decomposition.
Main Applications
In pharmaceuticals, picolinic acid is used as an intermediate in the synthesis of drugs, including those for treating metal deficiencies. Its chelating ability is exploited in formulations to enhance bioavailability. In agriculture, it serves as a precursor for herbicides and plant growth regulators. The chemical industry utilizes it in metal extraction and catalysis. Its broad applicability underscores its importance in B2B markets.
Safety and Storage
Picolinic acid should be stored in a cool, dry place, away from direct sunlight and moisture. Proper ventilation is recommended to prevent dust accumulation. Safety measures include wearing gloves, goggles, and masks to avoid skin contact, eye irritation, or inhalation. In case of exposure, rinse thoroughly with water and seek medical advice. Always refer to the Material Safety Data Sheet (MSDS) for detailed guidelines.
B2B Procurement Guide
When procuring picolinic acid, verify the CAS number (98-98-6) to ensure product authenticity. Purity specifications (e.g., ≥98%) should align with your application requirements. Bulk purchases typically offer cost advantages, so negotiate with suppliers for volume discounts. Reliable suppliers often provide technical support and MSDS documentation. Always request samples for quality testing before large-scale orders.
