Description

6-Aminoerythrosin is a chemically modified derivative of the xanthene dye erythrosin, characterized by the introduction of an amino functional group. This modification enhances its utility as a key synthetic intermediate and a versatile chromophore for advanced material science applications. It is primarily sought by research and development laboratories, as well as manufacturers in the specialty chemical and pharmaceutical sectors, for applications ranging from dye synthesis to biochemical labeling.

Application

• Synthetic Intermediate for the preparation of higher-order xanthene dyes and fluorescent probes.
• Biochemical Research as a potential labeling agent or stain in histology and microscopy.
• Material Science for the development of light-harvesting arrays and photoactive polymers.
• Analytical Chemistry as a reference standard or reagent in chromatographic and spectroscopic methods.
• Photodynamic Therapy Research for studying novel photosensitizer compounds.
• Industrial Dye Manufacturing as a precursor for specialized pigments and colorants.

Quality Control

Our 6-Aminoerythrosin is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets high-purity research-grade standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
