Description

5,5'-Dimethyl-9-Ethyl-3-(2-Hydroxyethyl)-3'-(3-Sulfatobutyl)Thiacarbocyanine Betaine is a high-purity, functionalized cyanine dye derivative designed for advanced applications requiring precise optical properties. This compound is valued for its excellent water solubility and reactive functional groups, making it a versatile intermediate for creating custom fluorescent probes and labels. It is primarily utilized by research institutions, diagnostic kit manufacturers, and biotechnology companies engaged in developing next-generation bioimaging and detection systems.

Application

• Fluorescent Labeling Reagent: Used as a key intermediate for synthesizing fluorescent conjugates with antibodies, proteins, and nucleic acids for bioassays.
• Biomedical Imaging: Serves as a precursor for near-infrared (NIR) dyes used in in vivo and in vitro diagnostic imaging applications.
• Diagnostic Kits: Incorporated into lateral flow assays and ELISA kits as a signal-generating component for sensitive detection.
• Flow Cytometry: Functionalized to create cell-permeant or cell-impermeant dyes for cell sorting and analysis.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer precursor due to its cyanine backbone and modifiable structure.
• Material Science: Applied in the development of functional polymers and coatings with specific light-absorption or emission characteristics.
• Sensor Development: Utilized to create chemical sensors that respond to specific analytes with a change in fluorescence.

Quality Control

Our production of 5,5'-Dimethyl-9-Ethyl-3-(2-Hydroxyethyl)-3'-(3-Sulfatobutyl)Thiacarbocyanine Betaine adheres to stringent quality protocols to ensure batch-to-batch consistency and high performance. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and spectrophotometry for optical property verification. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical specifications. We support cGMP and ISO 9001 compliant manufacturing upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from incompatible materials.
