Trimethyl[3-(trimethoxysilyl)propyl]ammonium chloride (50% in methanol)  (Synonyms: N-[3-(Trimethoxysilyl)propyl]-N,N,N-trimethylammonium chloride, 50% in methanol)

Trimethyl[3-(trimethoxysilyl)propyl]ammonium (N-[3-(Trimethoxysilyl)propyl]-N,N,N-trimethylammonium) chloride (50% in methanol) is a functional organic silane coupling agent and quaternary ammonium salt cationic functional monomer, which can be used for functionalizing mesoporous silica with electrochemical modified electrodes or surface chemical modification^[1][2].

Trimethyl[3-(trimethoxysilyl)propyl]ammonium chloride (50% in methanol) can be prepared as quaternized functional porous silica spheres through co-precipitation method^[1].
Trimethyl[3-(trimethoxysilyl)propyl]ammonium chloride (50% in methanol) can be used as a surface chemical modifier to construct a "positively charged quaternized mica substrate", which is used as a reference surface condition to study the conformational behavior of hyaluronic acid (HA) (HY-B0633A) in different surface charges/properties of polysaccharide molecules^[2].
