3-methyl-2-(1-methylethenyl)but-2-enoic acid, also known as β-ionone, is a naturally occurring organic compound that belongs to the class of terpenoids. It is a colorless to pale yellow liquid with a strong, sweet, floral odor, reminiscent of violets. β-ionone is an important component in the synthesis of various fragrances and flavors, particularly those mimicking the scent of violets, roses, and other floral notes. It is widely used in the perfumery and flavor industries due to its ability to enhance and stabilize the aroma of various products. The chemical structure of β-ionone consists of a 2,6-dimethyl-2,6-heptadien-4-one backbone, which contributes to its unique olfactory properties.

4412-05-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4412-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4412-05:
(6*4)+(5*4)+(4*1)+(3*2)+(2*0)+(1*5)=59
59 % 10 = 9
So 4412-05-9 is a valid CAS Registry Number.

A tandem radical macrocyclisation-transannular cyclisation approach towards the taxanes

Hitchcock, Stephen A.,Houldsworth, Stephen J.,Pattenden, Gerald,Pryde, David C.,Thomson, Nicholas M.,Blake, Alexander J.

, p. 3181 - 3206 (2007/10/03)

Separate treatment of the iodotrienedione 19 and the iododienynedione 38 with Bu3SnH-AIBN produces the corresponding taxane ring systems 25 (25-30%) and 56 (50-60%) respectively by way of tandem radical macrocyclisation-radical transannular cyc

Synthesis of Some Carboxylic Acid Analogs Cleaved between the C-2 and C-3 Bond of Tetramethylcyclopropanecarboxylic Acid, and Insecticidal Activities of Their Esters

Furuhata, Akimichi,Hirano, Masachika,Fujimoto, Izumi,Matsui, Masano

, p. 1633 - 1640 (2007/10/02)

Carboxylic acids with a cleaved type of cyclopropane ring between the C-2 and C-3 bond in tetramethylcyclopropanecarboxylic acid, the acid part of fenpropathrin, were prepared.Several of their esters with pyrethroidal alcohols exhibited good insecticidal activity, but their activity was a little weaker than that of fenpropathrin.
