Cyanine dyes are a class of organic functional dyes with excellent properties such as high molar absorption coefficients, broad spectral ranges, and high fluorescence quantum yields. These dyes are superior to other existing fluorescent labeling reagents such as rhodamine and fluorescein. Cyanine dyes are formed where two nitrogen atoms are joined by a polymethine chain. Both nitrogen atoms are independently part of a heteroaromatic moiety, such as imidazole, indole, thiazole, pyridine, pyrrole, quinoline, benzothiazole, and so on. Cyanine dyes are widely used in various scientific and industrial applications, including fluorescence imaging, photodynamic therapy, DNA detection, optical data storage, molecular labeling, and optoelectronic devices. Alfa Chemistry offers you the following two types of cyanine dyes:

Functional Dyes
Functional dyes refer to dyes that have special functions. The special function comes from the property of their molecules to undergo physical or chemical changes under the action of light, heat, or electric fields, such as the absorption of light and the production of fluorescence. Alfa Chemistry is dedicated to manufacturing and supplying an array of functional dyes to meet the different research, industrial, and commercial needs of our customers.
What We Offer
- Solvent Soluble Cyanine Dyes
Solvent soluble cyanine dyes are designed to dissolve readily in organic solvents such as ethanol, methanol and chloroform. This solubility makes them ideal for use in non-aqueous environments.
- Water Soluble Cyanine Dyes
Water soluble cyanine dyes usually have hydrophilic functional groups, such as sulfonate or quaternary ammonium moieties, which confer water solubility to the dye molecule. This solubility facilitates their use in biological systems and aqueous environments.
In addition to solvent soluble and water soluble cyanine dyes, we also offer miscellaneous dyes. Miscellaneous dyes play a crucial role in a wide range of applications. They are versatile, functional and adaptable to meet the diverse needs of various industries.
