STANNOUS CHLORIDE, 99 %, SnCl2, 100, 250, 500, Grams

Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride or stannic chloride (SnCl4)


A solution of tin(II) chloride containing a little hydrochloric acid is used for the tin-plating of steel, in order to make tin cans. An electric potential is applied, and tin metal is formed at the cathode via electrolysis.

Tin(II) chloride is used as a mordant in textile dyeing because it gives brighter colours with some dyes e.g. cochineal. This mordant has also been used alone to increase the weight of silk.

It is used as a catalyst in the production of the plastic polylactic acid (PLA).

It also finds a use as a catalyst between acetone and hydrogen peroxide to form the tetrameric form of acetone peroxide.

Tin(II) chloride also finds wide use as a reducing agent. This is seen in its use for silvering mirrors, where silver metal is deposited on the glass:

Sn2+ (aq) + 2 Ag+ → Sn4+ (aq) + 2 Ag (s)

A related reduction was traditionally used as an analytical test for Hg2+(aq). For example, if SnCl2 is added dropwise into a solution of mercury(II) chloride, a white precipitate of mercury(I) chloride is first formed; as more SnCl2 is added this turns black as metallic mercury is formed. Stannous chloride can be used to test for the presence of gold compounds. SnCl2 turns bright purple in the presence of gold (see Purple of Cassius).

When mercury is analyzed using atomic absorption spectroscopy, a cold vapor method must be used, and tin (II) chloride is typically used as the reductant.

In organic chemistry, SnCl2 is mainly used in the Stephen reduction, whereby a nitrile is reduced (via an imidoyl chloride salt) to an imine which is easily hydrolysed to an aldehyde.[6]

The reaction usually works best with aromatic nitriles Aryl-CN. A related reaction (called the Sonn-Müller method) starts with an amide, which is treated with PCl5 to form the imidoyl chloride salt.
The Stephen reduction

The Stephen reduction is less used today, because it has been mostly superseded by diisobutylaluminium hydride reduction.

Additionally, SnCl2 is used to selectively reduce aromatic nitro groups to anilines.[7]

SnCl2 also reduces quinones to hydroquinones.

Stannous chloride is also added as a food additive with E number E512 to some canned and bottled foods, where it serves as a color-retention agent and antioxidant.

SnCl2 is used in Radionuclide angiography to reduce the radioactive agent technetium-99m-pertechnetate to assist in binding to blood cells.

Finally, aqueous Stannous Chloride is used by many precious metals refining hobbyists as an indicator of Gold and Platinum group metals in solutions.[8]

Returns & exchanges

I can not offer returns, refunds or exchanges on chemical materials due to the fact that there is no guarantee that the material has not been tampered with and I can not resell it to someone else with confidence that I have the same materials that was originally purchased from my supplier. Therefore I repeat there are NO returns on chemical materials.

I offer exchanges only on Ceramic art for equal or greater value item. The buyer is required to pay to return the original item shipping and the new item shipping as well as 25% restocking fee. Also for clarity the Free shipping is no longer applicable on exchanged items. The new item will be shipped when the original item is received intact and the additional fees have been paid.
No item will be exchanged of a lesser value item with the buyer expecting refund.

Paintings are not returnable
