Alizarin Extra Pure

SHORT DESCRIPTION Alizarin Extra Pure is a high-grade anthraquinone-based dye, presented as a reddish-brown crystalline powder, renowned for its vivid coloration and strong affinity for metal ions. It is primarily used in analytical chemistry as a complexometric indicator, especially for detecting aluminum, calcium, and other metal ions through color change. Due to its exceptional purity, it is also employed in histological staining, textile research, and pigment synthesis where precision and consistency are critical. Alizarin Extra Pure offers excellent stability and intense coloration, making it ideal for scientific, educational, and specialized industrial applications. Proper storage in a cool, dry environment is essential to maintain its effectiveness and prevent degradation.

EDTA Disodium Salt Extra Pure

SHORT DESCRIPTION EDTA Disodium Salt Extra Pure is a high-purity chelating agent widely used in laboratory settings for complexometric titrations, metal ion sequestration, and buffer preparation. It binds strongly with divalent and trivalent metal ions like calcium, magnesium, and iron, making it essential in water hardness testing, biochemical research, and analytical chemistry. Its stability and effectiveness in controlling metal ion activity also make it valuable in molecular biology protocols and diagnostic reagent formulations.

Eriochrome Extra Pure

SHORT DESCRIPTION Eriochrome Extra Pure—typically referring to Eriochrome Black T—is a complexometric indicator primarily used in EDTA titrations to detect metal ions, especially calcium (Ca²⁺) and magnesium (Mg²⁺) in water hardness analysis. In its extra pure grade, this dye ensures sharp, precise endpoint detection by minimizing impurities that could cause background coloration or interferences in spectrophotometric or volumetric determinations. It functions by forming a wine-red complex with metal ions, which turns blue when the metal is sequestered by EDTA. Suitable for high-precision analytical chemistry, it should be stored away from light and moisture to preserve stability.

Oxalic Acid Extra Pure

SHORT DESCRIPTION Oxalic Acid Extra Pure is a high-purity, crystalline organic compound known for its strong reducing and chelating properties. Appearing as a white, odorless solid, it is highly soluble in water and widely utilized in both laboratory and industrial settings. This Extra Pure grade ensures reliable performance in analytical chemistry, metal cleaning, rust removal, and rare earth element processing. In the laboratory, it is commonly used to precipitate calcium ions and to prepare standard solutions for titration. In industries, Oxalic Acid is valued for its effectiveness in bleaching wood, cleaning marble, and removing iron stains from surfaces and textiles. Due to its toxicity and corrosiveness, it must be handled with appropriate personal protective equipment and stored securely in a cool, dry, well-ventilated area.
