Product Overview
Formic Acid, 90% AR, is a high-purity, colorless liquid with a pungent odor, widely recognized for its versatility in laboratory settings. This analytical reagent (AR) grade ensures minimal impurities, making it suitable for critical applications where precision is paramount. With a concentration of 90%, it serves as an effective reducing agent, solvent, and preservative in various chemical processes. Its strong acidic nature (pKa ~3.75) allows it to participate in esterification, hydrolysis, and other organic synthesis reactions. The liquid form ensures easy handling and accurate dispensing, while its stability under standard lab conditions makes it a reliable choice for prolonged storage. Formic acid’s compatibility with a wide range of organic and inorganic compounds further enhances its utility in complex experimental setups. Whether used in titration, sample preparation, or as a reagent in analytical techniques, this AR-grade formic acid delivers consistent performance, ensuring reproducible results in research and testing environments.
FAQs
1. What is the shelf life of 90% AR Formic Acid when stored properly?
When stored in a tightly sealed container away from moisture and direct sunlight, 90% AR Formic Acid typically retains its stability for up to 24 months from the date of manufacture. Always check the label for the exact expiry date and store it in a cool, well-ventilated area.
2. Can this formic acid be used as a solvent for polar compounds?
Yes, 90% AR Formic Acid is polar and can effectively dissolve a variety of polar organic and inorganic compounds. Its solvent properties make it useful in chromatography, extraction processes, and as a medium for reactions involving polar substrates.
3. Is this formic acid compatible with glass containers for long-term storage?
While formic acid can be stored in glass containers, prolonged exposure may cause slight etching or corrosion, especially at higher concentrations. For long-term storage, it is recommended to use containers made of high-density polyethylene (HDPE) or other chemically resistant materials to prevent contamination or container degradation.
4. What precautions should be taken when handling 90% AR Formic Acid?
Always wear appropriate personal protective equipment (PPE), including nitrile gloves, safety goggles, and a lab coat, when handling formic acid. Work in a fume hood or well-ventilated area to avoid inhalation of vapors, and avoid contact with skin or eyes, as it can cause irritation or burns.
5. Are there any known alternatives to formic acid for reducing applications?
Depending on the specific application, alternatives like acetic acid, hydrochloric acid, or sulfuric acid may be considered, though their reactivity and suitability vary. For organic synthesis, reagents like sodium borohydride or lithium aluminum hydride are often used for reduction, but they serve different mechanistic roles compared to formic acid.
