Description and Uses
Butyl trichlorosilane is a colorless liquid.Molecular weight = 191.57. Boiling point = 149℃; Flashpoint =45℃ (cc); 54℃ (oc). Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 2, Reactivity 2 . Insoluble in water; reactsviolently.
BTS can be coated on the glass substrate to introduce the surface alkyl, which can bind well with 2-methacryloyloxyethyl-4-azidobenzoate (MPAz) to convert hydrophophobic glass surfaces to superhydrophilic surfaces. It can functionalize zinc peroxide nanoparticle/polystyrene sulfonate (PSS) hybrid based sensors to improve the limit of detection by three-folds.
