Description

Tetrasodium [Mu-[[7,7'-(Carbonyldiimino)Bis[4-Hydroxy-3-[(2-Hydroxy-5-Sulphophenyl)Azo]Naphthalene-2-Sulphonato]](8-)]]Dicuprate(4-) is a complex, high-purity copper-containing azo dye intermediate. This compound is valued for its precise chemical structure, which is critical for synthesizing specialized dyes and pigments with excellent color fastness and complexing properties. It is primarily required by manufacturers in the textile, leather, and specialty chemical industries for producing high-performance colorants.

Application

• Key intermediate for the synthesis of high-grade, metal-complex azo dyes.
• Used in the production of dyes for textile fibers, particularly for wool, nylon, and silk.
• Manufacturing of dyes and pigments for the leather tanning and finishing industry.
• Precursor for specialty pigments used in inks and coatings requiring enhanced stability.
• Potential use in the formulation of analytical reagents and indicators in laboratory settings.
• Research and development of novel coordination compounds and colorants.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and purity. The product undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
