APTS

Description:

APTS, or 3-Aminopropyltriethoxysilane, is an organosilane compound characterized by its functional groups that include amine and ethoxy groups. It is commonly used as a coupling agent and surface modifier in various applications, particularly in the fields of materials science and nanotechnology. APTS enhances the adhesion between organic materials and inorganic substrates, making it valuable in the formulation of composites, coatings, and adhesives. The presence of the amine group allows for potential interactions with other chemical species, facilitating the formation of cross-linked networks. APTS is typically a colorless to pale yellow liquid with a characteristic odor, and it is soluble in organic solvents while being hydrolyzable in the presence of moisture, leading to the formation of silanol groups. This property enables it to bond effectively to surfaces, promoting improved mechanical and chemical properties in treated materials. Safety precautions should be observed when handling APTS, as it can be irritating to the skin and eyes.

APTS (8-Aminopyrene-1,3,6-trisulfonic acid, trisodium salt) is a fluorescent amine that is frequently used in the detection and differentiation of sugars or glycoconjugates like glycoproteins or certain hormones. Conjugation of the APTS with carbohydrates for example is performed by reductive amination of the aldehyde (or ketone) group of the sugar with APTS to form an imine, which is then reduced with sodium cyanoborohydride (NaBH3CN). The fluorophore remains stable under the reaction conditions described and provides a very sensitive detection method for the APTS-coupled molecule using laser-induced fluorescence.

8-Aminopyrene-1,3,6-trisulfonic acid trisodium salt (APTS) is a fluorescent probe that can be used to detect the presence of chloride ions. It has been found to be a sensitive and selective method for detecting chloride even at low concentrations. The detection limit of APTS is in the millimolar range. This method can be applied to a wide range of analytical chemistry techniques such as kinetic data, optical detection, Langmuir adsorption isotherm, and gravimetric analysis.
