Norcamphor Specification

Norcamphor(CAS NO.497-38-1) is a chemical compound, classified as a ketone, which is an analog of camphor without the three methyl groups. Itis a colorless to white adhering crystals. It is found in wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in Asia (particularly in Borneo and Taiwan) and also of Dryobalanops aromatica, a giant of the Bornean forests. It also occurs in some other related trees in the laurel family, notably Ocotea usambarensis. It can also be synthetically produced from oil of turpentine. It is used as a chemical building block in organic synthesis.

Physical properties about Norcamphor are: (1)ACD/LogP: 0.892; (2)ACD/LogD (pH 5.5): 0.89; (3)ACD/LogD (pH 7.4): 0.89; (4)ACD/BCF (pH 5.5): 2.80; (5)ACD/BCF (pH 7.4): 2.80; (6)ACD/KOC (pH 5.5): 72.79; (7)ACD/KOC (pH 7.4): 72.79; (8)#H bond acceptors: 1; (9)Index of Refraction: 1.511; (10)Molar Refractivity: 30.465 cm3; (11)Molar Volume:101.71 cm3; (12)Polarizability: 12.077 10-24cm3; (13)Surface Tension: 37.9020004272461 dyne/cm; (14)Density: 1.083 g/cm3; (15)Flash Point: 33.889 °C; (16)Enthalpy of Vaporization: 40.641 kJ/mol; (17)Boiling Point: 169.999 °C at 760 mmHg; (18)Vapour Pressure: 1.5 mmHg at 25°C

When you are using Norcamphor, please be cautious about it as the following:
1. Keep away from sources of ignition - No smoking;
2. Take precautionary measures against static discharges;
