Q1: What is the CAS Number for Anhydrous Tin Tetrachloride?
A: The CAS Registry Number is 7646-78-8.
Q2: How should Anhydrous Tin Tetrachloride be handled to prevent hydrolysis during storage or transfer?
A: Store under inert atmosphere (N₂ or Ar) in sealed, moisture-proof containers; use dry-gas purged syringes or cannula techniques for transfer; avoid exposure to ambient humidity above 30% RH.
Q3: How does Anhydrous Tin Tetrachloride compare to Titanium Tetrachloride (TiCl₄) as a Lewis acid catalyst?
A: SnCl₄ exhibits milder Lewis acidity than TiCl₄, offering better functional group tolerance and reduced risk of substrate decomposition; it also demonstrates superior selectivity in asymmetric aldol-type reactions when paired with chiral ligands.
Q4: Is Anhydrous Tin Tetrachloride compliant with REACH and RoHS regulations?
A: Yes — supplied with full REACH registration (EU No. 01-2119458032-42-XXXX) and RoHS-compliant documentation; contains no SVHC substances above threshold levels per current Annex XIV.
