Product Name – DRAGENDORFF’S REAGENT Quantity/Pack Size – 125 ml Form – Liquid (Solution) Grade – Laboratory Reagent Grade Application – Alkaloid detection, qualitative analysis
Product Overview
Dragendorff’s reagent is a specialized chemical solution designed for the qualitative detection of alkaloids in laboratory settings. This orange-red liquid forms insoluble precipitates with alkaloids, making it indispensable for preliminary screening in chemical analysis. The reagent consists of a complex of bismuth nitrate, potassium iodide, and acetic acid, ensuring high sensitivity and specificity in reactions. Its laboratory reagent grade guarantees consistent performance, free from impurities that could interfere with results. The solution is stable under standard storage conditions, maintaining efficacy for extended periods when kept in a tightly sealed container. Ideal for use in thin-layer chromatography (TLC) and spot tests, this reagent provides clear visual confirmation of alkaloid presence, aiding in rapid identification. The 125 ml pack size offers sufficient volume for multiple tests while minimizing waste. As a non-hazardous formulation when handled properly, it aligns with standard lab safety protocols, though basic protective measures are recommended during use.
FAQs
1. What is the shelf life of Dragendorff’s reagent?
The reagent remains stable for 12-18 months when stored in a cool, dark place with the cap tightly closed. Degradation may occur if exposed to light or moisture.
2. Can this reagent detect all types of alkaloids?
Dragendorff’s reagent reacts with most alkaloids, but sensitivity varies. Some tertiary alkaloids may require higher concentrations for visible precipitation.
3. What precautions should be taken during storage?
Store away from direct sunlight and heat sources. Keep the container sealed to prevent evaporation and contamination.
4. Is this reagent compatible with TLC plates?
Yes, it is commonly used as a spraying reagent for TLC plates to visualize alkaloid spots after development.
5. What alternatives exist for alkaloid detection?
Mayer’s reagent and Wagner’s reagent are common alternatives, though Dragendorff’s is preferred for its broader reactivity range.
