Specification
The n-Butyltin hydroxide oxide with the cas number 2273-43-0, is also called (1) 1-Butanestannonic acid ; (2) Butylhydroxytin oxide ; (3) Butylstannoic acid ; (4) Butylstannonic acid ; (5) Butyltin hydroxide oxide ; (6) Mono-N-butyltin oxide ; (7) Systematic Name ; (8) Butylhydroxyoxostannane ; (9) Stannane, butylhydroxyoxo- and so on. n-Butyltin hydroxide oxide belongs to the following product categories: (1)Alkyl Metals; (2)Classes of Metal Compounds; (3)Grignard Reagents & Alkyl Metals; (4)Sn (Tin) Compounds; (5)Synthetic Organic Chemistry; (6)Typical Metal Compounds.
When you are using this chemical, please be cautious about it as the following:
Firstly, n-Butyltin hydroxide is irritating not only to eyes, respiratory system but also is irritating to skin. Hence, when using it, please wear suitable gloves and eye/face protection to prevent you from such harm. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Solid-state reaction assisted by microwave between equimolar quantities of sterically encumbered 3,5-di-tert-butylsalicylic acid (H-2-DTBSA) and n-Butyltin hydroxide oxide results in the formation of hexameric drum shaped stannoxane [(BuSn)-Bu-n(O)(H-DTBSA)].
