Description

Application

Tin(II) chloride dehydrate may be used in conversion of organomercurials into inorganic mercury determined using flow injection-cold vapor atomic absorption spectrometry. It may also be used in determination of total mercury content, using atomic fluorescence spectroscopy and mercury speciation was performed using gas chromatography inductively coupled plasma mass spectrometry (GC-ICPMS).

General description

Tin(II) chloride dehydrate converts conjugated dioxolones to aldehyde. It helps as a catalyst in multi-component condensation reaction from aromatic aldehydes, 2-aminopyridines and isonitriles which results in reasonable yield and reducing the reaction time.
