Specification

The Metaldehyde, with the CAS registry number 108-62-3, is also known as Metaldehyde. Its EINECS registry number is 203-600-2. This chemical's molecular formula is C₈H₁₆O₄ and molecular weight is 176.21. What's more, both its IUPAC name and systematic name are the same which is called 2,4,6,8-Tetramethyl-1,3,5,7-tetroxocane. It is formed at temperatures below 0 °C in the presence of dry hydrogen chloride or pyridine-hydrogen bromide. The metaldehyde crystallizes from solution and is separated from the paraldehyde by filtration. Metaldehyde is a chemical that is commonly used as a pesticide against slugs, snails, and other gastropods.

Physical properties about Metaldehyde are: (1)ACD/LogP: 1.356; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.36; (4)ACD/LogD (pH 7.4): 1.36; (5)ACD/BCF (pH 5.5): 6.32; (6)ACD/BCF (pH 7.4): 6.32; (7)ACD/KOC (pH 5.5): 130.29; (8)ACD/KOC (pH 7.4): 130.29; (9)#H bond acceptors: 4; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 36.92 Å²; (13)Index of Refraction: 1.386; (14)Molar Refractivity: 43.7 cm³; (15)Molar Volume: 186.07 cm³; (16)Polarizability: 17.324×10^-24cm³; (17)Surface Tension: 24.969 dyne/cm; (18)Density: 0.947 g/cm³; (19)Flash Point: 71.073 °C; (20)Enthalpy of Vaporization: 41.287 kJ/mol; (21)Boiling Point: 194.283 °C at 760 mmHg; (22)Vapour Pressure: 0.622 mmHg at 25 °C.
