Sec.  184.1845  Stannous chloride (anhydrous and dihydrated).

    (a) Stannous chloride is anhydrous or contains two molecules of 
water of hydration. Anhydrous stannous chloride (SnCl2, CAS 
Reg. No. 7772-99-8) is the chloride salt of metallic tin. It is prepared 
by reacting molten tin with either chlorine or gaseous tin 
tetrachloride. Dihydrated stannous chloride 
(SnCl2[middot]2H2O, CAS Reg. No. 10025-0969-091) 
is the chloride salt of metallic tin that contains two molecules of 
water. It is prepared from granulated tin suspended in water and 
hydrochloric acid or chlorine.
    (b) Both forms of the ingredient meet the specifications of the Food 
Chemicals Codex, 3d Ed. (1981), p. 312, which is incorporated by
