Beschreibung

Allgemeine Beschreibung

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.

Anwendung

Tin(II) chloride dehydrate may be used:

• As a reducing agent for the determination of hydride forming species by AAS.
• In the conversion of organomercurials into inorganic mercury determined using a flow injection-cold vapor atomic absorption spectrometry
• In the determination of total mercury content, using atomic fluorescence spectroscopy and mercury speciation was performed using gas chromatography inductively coupled plasma mass spectrometry (GC-ICPMS).
