Formic Acid 100% is a high-purity, pharmacopeial-grade organic acid used in pharmaceutical and analytical laboratories for chemical synthesis, chromatography, pH adjustment, and preparation of analytical reagents and mobile phases.
🏭⚗️ Production
Produced under strictly controlled conditions to ensure high purity, minimal water content, and absence of metallic or organic impurities. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or decomposition. Quality is verified according to pharmacopeial and analytical standards for acid strength and purity.
🔬 Properties
A clear, colorless, fuming liquid with a sharp, pungent odor. Strongly acidic, corrosive, and completely miscible with water and many organic solvents. Chemically stable under proper storage conditions but decomposes upon prolonged heating or exposure to strong oxidizers.
🧪 Applications
Used in pharmaceutical and analytical laboratories for pH control, as a solvent and mobile phase additive in chromatography (especially LC and LC–MS), and in the synthesis of esters, salts, and other organic intermediates. Suitable for analytical and preparative procedures requiring anhydrous, concentrated acid.
⚠️ Safety
Highly corrosive and toxic by contact, inhalation, or ingestion. Can cause severe burns to skin and eyes. Handle with acid-resistant gloves, goggles, face shield, and protective clothing in a fume hood or well-ventilated area. Avoid contact with bases, oxidizing agents, and reactive metals. Store in a cool, dry, tightly sealed, corrosion-resistant container away from heat and moisture. Dispose of according to laboratory and environmental safety regulations.
