Specification

The Dibutyldichlorostannane, with the CAS registry number 683-18-1 and EINECS registry number 211-670-0, has the systematic name of dibutyl(dichloro)stannane. It is a kind of white to beige crystalline low melting mass, and belongs to the following product categories: Alkyl Metals; Biochemistry; Classes of Metal Compounds; Grignard Reagents & Alkyl Metals; Reagents for Oligosaccharide Synthesis; Sn (Tin) Compounds; Synthetic Organic Chemistry; Typical Metal Compounds. And the molecular formula of the chemical is C₈H₁₈Cl₂Sn. What's more, it is always used as a catalyst and intermediate.

The physical properties of Dibutyldichlorostannane are as followings: (1)ACD/LogP: 1.01; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.01; (4)ACD/LogD (pH 7.4): 1.01; (5)ACD/BCF (pH 5.5): 3.43; (6)ACD/BCF (pH 7.4): 3.43; (7)ACD/KOC (pH 5.5): 84.03; (8)ACD/KOC (pH 7.4): 84.03; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 6; (12)Polar Surface Area: 0 Å²; (13)Flash Point: 107.8 °C; (14)Enthalpy of Vaporization: 49.31 kJ/mol; (15)Boiling Point: 275.3 °C at 760 mmHg; (16)Vapour Pressure: 0.0086 mmHg at 25°C.

You should be cautious while dealing with this chemical. It is toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, and it is also toxic if swallowed. What's more, it may cause burns. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible); Avoid release to the environment. Refer to special instructions safety data sheet.
