Description

Mordant Yellow 10 is a synthetic organic dye belonging to the azo dye class, widely recognized for its use as a metallochromic indicator and a biological stain. Its primary commercial value lies in its ability to form stable, colored complexes with metal ions, making it indispensable for analytical and histological applications. This product is essential for industries and laboratories involved in metal analysis, biological research, and specialized textile dyeing processes where precise colorimetric detection is required.

Application

• Metallochromic Indicator: Used in complexometric titrations, particularly for the determination of calcium and magnesium ions in water hardness testing and other analytical procedures.
• Biological Staining: Employed in histology and microscopy for staining calcium deposits in tissues, such as in von Kossa staining techniques.
• Textile Dyeing (Mordant Dye): Functions as a dye for wool, silk, and nylon when used in conjunction with metal salts (mordants) like aluminum or chromium to form insoluble colored complexes on the fiber.
• Research & Development: Serves as a reagent in chemical and biochemical research for studying metal ion interactions and chelation chemistry.
• Industrial Analysis: Applied in various industrial quality control labs for the colorimetric detection and quantification of specific metal ions in process streams or products.

Quality Control

Our Mordant Yellow 10 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high performance. Each lot undergoes comprehensive analytical testing, including identification (IR), purity assay (HPLC/Titration), and checks for relevant impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product stability.
