Specification

o-Phenylenediamine, with the CAS NO.95-54-5, has the synonyms of 1,2-Benzenediamine; 1,2-Diaminobenzene; C.I. 76010; C.I. Oxidation base 16; Orthamine. o-Phenylenediamine is an organic compound with the formula C₆H₄(NH₂)₂. It condenses with ketones and aldehydes to give rise to a variety of useful products. Condensation of substituted o-phenylenediamine with various diketones is used in the preparation of a variety of pharmaceuticals.

Physical properties about o-Phenylenediamine are: (1)ACD/LogP: 0.052; (2)ACD/LogD (pH 5.5): 0.02; (3)ACD/LogD (pH 7.4): 0.05; (4)ACD/BCF (pH 5.5): 1.00; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 23.31; (7)ACD/KOC (pH 7.4): 25.41; (8)#H bond acceptors: 2 ; (9)#H bond donors: 4; (10)#Freely Rotating Bonds: 2; (11)Index of Refraction: 1.66; (12)Molar Refractivity: 34.725 cm³; (13)Molar Volume: 93.994 cm³; (14)Polarizability: 13.766 10-24cm³; (15)Surface Tension: 57.5979995727539 dyne/cm; (16)Density: 1.15 g/cm³; (17)Flash Point: 124.929 °C; (18)Enthalpy of Vaporization: 49.454 kJ/mol; (19)Boiling Point: 256.999 °C at 760 mmHg; (20)Vapour Pressure: 0.0149999996647239 mmHg at 25°C

Preparation of o-Phenylenediamine: Most commonly 2-nitrochlorobenzene is treated with ammonia, and the resulting 2-aminonitrobenzene is then hydrogenated:
ClC₆H₄NO₂ + 2 NH₃ → H₂NC₆H₄NO₂+ NH₄Cl
H₂NC₆H₄NO₂+ 3 H₂ → H₂NC₆H₄NH₂+ 2 H₂O

When you are using this chemical, please be cautious about it as the following:
1. After contact with skin, wash immediately with plenty of ... (to be specified by the manufacturer);
2. Wear suitable protective clothing and gloves;
3. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible);
4. This material and/or its container must be disposed of as hazardous waste;
5. Avoid release to the environment. Refer to special instructions safety data sheet;
6. Keep locked up and out of the reach of children;
