Specification

The Hexazinone, with the CAS registry number 51235-04-2 and EINECS registry number 257-074-4, has the systematic name of 3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine-2,4(1H,3H)-dione. And the molecular formula of this chemical is C₁₂H₂₀N₄O₂. This white crystalline solid can soluble in water, and rapidly decomposed in solution by strong acids and bases. What's more, it is a known and pervasive groundwater contaminant, due to its high water solubility. In addition, it is used to control grasses and broadleaf and woody plants.

The physical properties of Hexazinone are as following: (1)ACD/LogP: 1.85; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.85; (4)ACD/LogD (pH 7.4): 1.85; (5)ACD/BCF (pH 5.5): 14.99; (6)ACD/BCF (pH 7.4): 15; (7)ACD/KOC (pH 5.5): 241.68; (8)ACD/KOC (pH 7.4): 241.77; (9)#H bond acceptors: 6; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 2; (12)Polar Surface Area: 56.22 Å²; (13)Index of Refraction: 1.612; (14)Molar Refractivity: 68.81 cm³; (15)Molar Volume: 197.8 cm³; (16)Polarizability: 27.28×10^-24cm³; (17)Surface Tension: 47.3 dyne/cm; (18)Density: 1.27 g/cm³; (19)Flash Point: 155.1 °C; (20)Enthalpy of Vaporization: 57.56 kJ/mol; (21)Boiling Point: 332.8 °C at 760 mmHg; (22)Vapour Pressure: 0.000142 mmHg at 25°C.

Hexazinone can be prepared as follows:
