Product Overview
Heptafluorobutyric anhydride (HFBA) is a highly reactive fluorinated reagent used extensively in analytical chemistry for derivatization processes. With a purity of 98% or higher, this compound ensures accurate and reliable results in gas chromatography-mass spectrometry (GC/MS) applications. Its unique fluorinated structure enhances volatility and thermal stability, making it ideal for modifying polar compounds to improve chromatographic separation and detection sensitivity. The anhydrous nature of this reagent minimizes side reactions, ensuring clean derivatization with minimal background interference. Packaged in a sealed container to prevent moisture absorption, this high-purity HFBA maintains its reactivity over extended storage periods when handled under inert conditions. The colorless liquid form allows for easy handling and precise volume measurements, while its strong electron-withdrawing properties facilitate efficient acylation reactions. Whether used for small-scale research or routine laboratory procedures, this reagent delivers consistent performance for demanding analytical applications.
FAQs
1. What is the shelf life of heptafluorobutyric anhydride when stored properly?
When stored in a tightly sealed container under dry, inert conditions at room temperature, heptafluorobutyric anhydride typically maintains its purity and reactivity for 12-24 months from the date of manufacture.
2. Can this reagent be used with aqueous samples directly?
No, heptafluorobutyric anhydride reacts violently with water, producing heptafluorobutyric acid and heat. Samples must be thoroughly dried or extracted into an organic solvent before derivatization.
3. What safety precautions should be taken when handling this chemical?
Always handle in a fume hood wearing appropriate PPE including gloves, goggles, and lab coat. Avoid inhalation of vapors and skin contact, as the reagent is highly corrosive and can cause severe burns.
4. Is this product compatible with glass vials for storage?
Yes, but ensure the glass is thoroughly dried and the vial is tightly sealed with a PTFE-lined cap to prevent moisture contamination and reaction with the glass surface over time.
5. What alternatives exist if I need a less reactive fluorinated anhydride?
Trifluoroacetic anhydride offers a milder alternative with similar derivatization properties, though it may provide different selectivity in certain applications compared to heptafluorobutyric anhydride.
