12026-24-3 Usage
Description
Tin dihydroxide, also known as stannous oxide hydrate or SnO·H2O, is a white amorphous crystalline product obtained by treating stannous chloride solutions with alkali. It has a molecular weight of 152.7 and exhibits unique chemical properties.
Uses
Used in Immersion Tinning:
Tin dihydroxide is used as a chemical precursor in the immersion tinning process for [application reason]. The stannite solutions, which decompose readily to alkali-metal stannates and tin, have been utilized industrially for this purpose.
Check Digit Verification of cas no
The CAS Registry Mumber 12026-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,2 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12026-24:
(7*1)+(6*2)+(5*0)+(4*2)+(3*6)+(2*2)+(1*4)=53
53 % 10 = 3
So 12026-24-3 is a valid CAS Registry Number.

Infrared spectra of M(OH)1,2,4 (M = Pb, Sn) in solid argon
Wang, Xuefeng,Andrews, Lester
, p. 9013 - 9020 (2008/10/09)
Infrared absorptions for the matrix-isolated lead and tin hydroxides M(OH), M(OH)2 and M(OH)4 (M = Pb, Sn) were observed in laser-ablated metal atom reactions with H2O2 during condensation in excess argon. The major M(OH)2 product was also observed with H2 and O2 mixtures, which allowed the substitution of 18O2. The band assignments were confirmed by appropriate D2O2, D2, 16O 18O, and 18O2 isotopic shifts. MP2 and B3LYP calculations were performed to obtain molecular structures and to reproduce the infrared spectra. The minimum energy structure found for M(OH)2 has Cs symmetry and a weak intramolecular hydrogen bond. In experiments with Sn, HD, and O2, the internal D bond is favored over the H bond for Sn(OH)(OD). The Pb(OH)4 and Sn(OH)4 molecules are calculated to have S4 symmetry and substantial covalent character.
