Description

Cuprate, [[2-[[.Alpha.-[3-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-2-Hydroxy, 5-Sulfophenyl] Azo]Phenylmethylene]Hydrazino]-4-Sulfobenzoato], Disodium is a high-purity, water-soluble copper complex dye characterized by its specific azo-triazine structure. This compound is engineered for applications requiring precise color formation and metal chelation, offering excellent stability and performance consistency. It is primarily utilized in specialized industrial sectors such as analytical chemistry, textile dyeing, and as a potential intermediate for functional dyes and pigments.

Application

• Textile Dyeing and Printing: As a metal-complex dye for coloring natural and synthetic fibers, particularly where wash-fastness and light-fastness are critical.
• Analytical Reagent: Used in laboratory settings as a colorimetric reagent or indicator for the detection and quantification of specific analytes.
• Functional Dye Intermediate: Serves as a key precursor in the synthesis of advanced dyes and pigments for inks, coatings, and plastics.
• Biological Staining: Potential application in histological staining for microscopy due to its metal-binding and chromogenic properties.
• Catalyst Research: Investigated as a ligand or component in catalytic systems for organic synthesis.
• Photographic and Imaging Chemicals: Can be employed in specialized photographic processes or as a sensitizer.

Quality Control

Our production of this specialty dye adheres to rigorous quality control protocols to ensure batch-to-batch consistency and purity. Each lot is tested against established specifications for identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing the results of these tests, including HPLC purity, heavy metal content, and spectroscopic identification, is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture.
