6284-82-8 Usage
General Description
The chemical compound (2E)-5,7,7-trimethyl-2-(1,3,3-trimethylbutyl)oct-2-enal, also known as citral, is a fragrant aldehyde found in a variety of essential oils, including lemon, lime, and lemongrass. It is widely used in the fragrance and flavor industries due to its pleasant citrus scent. Citral is also known for its antimicrobial properties and has been used in traditional medicine to treat various infections. Additionally, it has potential applications in the food industry as a flavoring agent and in the cosmetic industry as a fragrance component. However, it can be a skin and respiratory irritant and should be handled with care.
Check Digit Verification of cas no
The CAS Registry Mumber 6284-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,8 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6284-82:
(6*6)+(5*2)+(4*8)+(3*4)+(2*8)+(1*2)=108
108 % 10 = 8
So 6284-82-8 is a valid CAS Registry Number.

Aldol Reaction and Robinson-Type Annelation Catalyzed by Lanthanoid Triisopropoxides
Okano, Tamon,Satou, Yoshikazu,Tamura, Motoshi,Kiji, Jitsuo

Lanthanoid triisopropoxides are active catalysts for aldol reactions.Aldehydes give the corresponding β-hydroxyaldehydes at low temperatures in good yields, whereas ketones are less reactive, but form condensation products at high temperatures.Exceptionally, γ- or δ-diketones easily undergo condensation to give five- and six-membered unsaturated ketones in high yields.The lanthanoid propoxides, catalyzing the Michael addition of ketones to α,β-unsaturated ketones, which give δ-diketones, are also good catalysts for the Robinson-type annelation.In these reactions, the catalytic activity of the lanthanum propoxide is higher than those of the heavy lanthanoid propoxides, and is almost comparable to that of sodium isopropoxide.Since aluminum triisopropoxide shows poor activity, the lanthanoid propoxides are considerably basic for trivalent metal alkoxides.
