Dyes are colored materials because they absorb only some certain wavelengths of visible light and have an affinity to the substrate they are used on. Dyes are commonly used in aqueous solutions and may require mordant to increase the fastness of the dyes to the fibers. Dyes are generally soluble in water, and some dyes can be made insoluble by adding salts to produce lake pigments. Dyes are classified according to their solubility and chemical properties. Alfa Chemistry is committed to providing a wide range of dyes. There are also many other dyes such as cationic dyes, direct dyes, neutral dyes, solvent dyes, coupler and pigments at Alfa Chemistry.

Organic building blocks are mainly used for bottom-up modular assembly of metal-organic frameworks, organic molecular constructs, and supra-molecular complexes. Using organic building blocks ensures strict control of what a final compound will be.

Alfa Chemistry can offer a wide variety of organic building blocks including alkanes, alkenes, alkynes, arenes, arsenic compounds, carbonyl compounds, halogenated hydrocarbons, nitrogen compounds, organic phosphine compounds, organic silicon compounds, oxygen compounds and selenium compounds.

Surfactants are compounds that lower the surface tension between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants can be used as detergents, wetting agents, emulsifiers, foaming agents and dispersants. Surfactants are usually amphiphilic organic compounds, which means that they contain both hydrophobic groups and hydrophilic groups. Thus, surfactants contain both water-insoluble and water-soluble components. In the case where water is mixed with oil, the surfactant will diffuse into the water and adsorb at the interface between air and water or at the interface between oil and water. Water-insoluble hydrophobic groups can stick out of the bulk aqueous phase into the air-oil phase, while the water-soluble groups remain in the aqueous phase. Surfactants have a class of flexible applications due to a series of physicochemical effects, and are used in wide range of fine chemical products. In addition to being detergents in daily life, other applications of surfactants can cover almost all fine chemical fields. Learn more at https://www.alfa-chemistry.com/products/surfactant-124.htm.

Graphene - Properties & Applications

Pheromones are substances produced as messengers that affect the behavior of other insects, animals and members of the same species. In order to engage in routine activities, each species of insects relies on more than one hundred chemicals during its life. Pheromones can be mainly divided into the following species in function: trace pheromones (to locate a food source), aggregation pheromones (to find individuals of the same species), alarm pheromones (to warn any sort of danger) and sex pheromones (to attract adults of the opposite sex for mating). Simple insect pheromones are straight chain compounds, including hydrocarbon, alcohol, and esterandaldehyde. Others are side chain compounds. In addition, ketones and epoxy compounds are also included. Alfa Chemistry offers a wide range of different insect pheromones that respond to control pests effectively and respectfully with the environment.

Steroids are important organic compounds based on the fundamental saturated tetracyclic hydrocarbon: 1,2-cyclopentanoperhydrophenanthrene (gonane or sterane). These four cycloalkane rings consist of 17 carbon atoms that are bound together, which include three cyclohexane rings and one cyclopentane ring. When varying the functional groups attached to the basic steroid rings or changing the number of double bonds in the carbon rings, we can get a lot different steroids. Alfa Chemistry has an advantage over other suppliers offering series of steroidal compounds, which encompass compounds of vital importance to life and have great variations in structure. Alfa Chemistry can provide two categories, natural steroids and anabolic steroids. Learn more at https://www.alfa-chemistry.com/products/steroidal-compounds-8.htm
