L-α-Curcumen, also known as (-)-α-Curcumen, is a naturally occurring sesquiterpene compound found in various plants, particularly in the essential oils of Curcuma zedoaria and Cyperus rotundus. It is characterized by a unique bicyclic structure with a cyclohexane ring fused to a cyclobutane ring, and it exhibits a chiral center, which gives rise to its L-enantiomeric form. L-α-Curcumen has been studied for its potential biological activities, including anti-inflammatory, antioxidant, and anticancer properties. Its chemical formula is C15H24, and it has a molecular weight of 204.35 g/mol. The compound is of interest in the field of natural product chemistry and pharmacology due to its potential therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 4548-25-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4548-25:
(6*4)+(5*5)+(4*4)+(3*8)+(2*2)+(1*5)=98
98 % 10 = 8
So 4548-25-8 is a valid CAS Registry Number.

Tomato-produced 7-epizingiberene and R-curcumene act as repellents to whiteflies

Bleeker, Petra M.,Diergaarde, Paul J.,Ament, Kai,Schütz, Stefan,Johne, Bettina,Dijkink, Jan,Hiemstra, Henk,De Gelder, René,De Both, Michiel T.J.,Sabelis, Maurice W.,Haring, Michel A.,Schuurink, Robert C.

, p. 68 - 73 (2011)

How whiteflies (Bemisia tabaci) make the choice for a host plant prior to landing, is not precisely known. Here we investigated whether they respond to specific volatiles of tomato. Zingiberene and curcumene were purified from Solanum habrochaites (PI1278

Stereospecific Hydrogenolysis of Lactones: Application to the Total Syntheses of (R)-ar-Himachalene and (R)-Curcumene

Spielmann, Kim,De Figueiredo, Renata Marcia,Campagne, Jean-Marc

, p. 4737 - 4743 (2017/05/12)

A straightforward strategy for the syntheses of curcumene and ar-himachalene is reported. Synthetic highlights include a catalytic and asymmetric vinylogous Mukaiyama reaction and a stereospecific hydrogenolysis of a tertiary benzylic center using Pd/C or Ni/Raney catalysts. Notably, using Ni/Raney, the stereoselectivity outcome (inversion vs retention) of the hydrogenolysis depends on the tertiary benzylic alcohol substitution.

Page/Page column 39; 40, (2010/09/18)

The invention provides a method for controlling whiteflies which comprises the steps of: providing a composition comprising or consisting of R-curcumene and optionally further beta-myrcene, para-cymene, gamma-terpinene, alpha-terpinene, alpha-phellandrene zingiberene and/or 7-epi-zingiberene; and adding said composition one or more times to a plurality of crop plants. The method can be combined with the use of attractant compositions comprising beta-phellandrene, limonene and/or 2-carene, and optionally adding said composition one or more times to one or more trap plants and/or trap materials.
