Specification

The 4-Fluorobenzylamine, with the CAS registry number 140-75-0 and EINECS registry number 205-430-4, has the systematic name of 1-(4-fluorophenyl)methanamine. It is a kind of colorless to light yellow liquid, and belongs to the following product categories: Anilines, Aromatic Amines and Nitro Compounds; C7; Nitrogen Compounds. And the molecular formula of the chemical is C₇H₈FN. What's more, it is always used as intermediate in the pharmaceutical and pesticideindustry, such as astemizole.

The physical properties of 4-Fluorobenzylamine are as followings: (1)ACD/LogP: 1.14; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -1.88; (4)ACD/LogD (pH 7.4): -0.75; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1.28; (9)#H bond acceptors: 1; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 2; (12)Polar Surface Area: 3.24 Å²; (13)Index of Refraction: 1.522; (14)Molar Refractivity: 34.69 cm³; (15)Molar Volume: 113.6 cm³; (16)Polarizability: 13.75×10^-24cm³; (17)Surface Tension: 36.9 dyne/cm; (18)Density: 1.101 g/cm³; (19)Flash Point: 73.3 °C; (20)Enthalpy of Vaporization: 42.05 kJ/mol; (21)Boiling Point: 184.3 °C at 760 mmHg; (22)Vapour Pressure: 0.738 mmHg at 25°C.

Synthesis method: Firstly, add hydrazine hydrate solution to the mixed solution of N-(4-fluorophenyl-methyl)phthalimide and anhydrous alcohol, heat to reflux for 1 hour. Secondly, add excess HCl to make it precipitated out, and then neutralize it with NaOH. After a series of extraction, drying, distillation, you can get the product.

You should be cautious while dealing with this chemical. It may cause burns, and it is harmful by inhalation, in contact with skin and if swallowed. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection; In case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; Take off immediately all contaminated clothing; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
