127-41-3 Usage

Description

Different sources of media describe the Description of 127-41-3 differently. You can refer to the following data:
1. The alpha-ionone is the alpha form of ionone. The ionones denote a series of chemical substances belonging to rose ketones including carotene, damascenes and damascenones. It is found in various kinds of essential oils contained in some flowers such as violet. Ionone has three forms including alpha-, beta and gamma-. The alpha-ionone has the aroma odor of violet, which has been widely used in daily chemical flavor and tobacco-used flavor. The alpha-ionone can be made from the thermal decomposition of carotene.
2. α-Ionone has a characteristic violet-like odor. α-Ionone may be prepared by condensing citral with acetone to form pseudoionone, which is then cyclized by acid-type reagents.

Chemical Properties

Different sources of media describe the Chemical Properties of 127-41-3 differently. You can refer to the following data:
1. α-Ionone has a warm, woody, berry characteristic violet-like odor. The composition of commercial ionones varies widely in the proportion of α- and β-isomers; the specifications given below refer to the best grade of α- and β-ionones and to a commercial grade that contains both α- and β-ionones.
2. clear yellow liquid

Uses

Different sources of media describe the Uses of 127-41-3 differently. You can refer to the following data:
1. An aroma compound commonly found in essential oils such as rose oil. It is a degradation products of caratenoids produced by caratenoid cleavage dioxygenases (CCD).
2. alpha-Ionone, is used in many floral accords. Gives a violet flower nuance to compositions, but is also used in rose, woody, amber, balsamic, and powdery fragrances. It is also used in perfumery, flavoring, and vitamin A (retinol) production for cosmetics and toiletries. beta isomer shows a less floral odor than the alpha. It has good substantivity and is used in all areas of perfumery.

General Description

α-lonone is a C13 norterpenoid formed from the degradation of carotenoids. It is an important fragrance compound used in perfume industries due to its characteristic fine violet and rose scents. Commercially α-lonone is used in cosmetics, personal care products, detergents, etc. As a flavoring agent, it is widely used in various beverages including wine and tea.

Purification Methods

Purify α-ionone through a spinning band fractionating column. The semicarbazone has m 157-157.5o (from EtOH) and [] D +433o (c 4,

Check Digit Verification of cas no

The CAS Registry Mumber 127-41-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127-41:
(5*1)+(4*2)+(3*7)+(2*4)+(1*1)=43
43 % 10 = 3
So 127-41-3 is a valid CAS Registry Number.

Photocaged Hydrocarbons, Aldehydes, Ketones, Enones, and Carboxylic Acids and Esters that Release by the Norrish II Cleavage Protocol and Beyond: Controlled Photoinduced Fragrance Release

Griesbeck, Axel G.,Porschen, Bj?rn,Kropf, Christian,Landes, Agnieszka,Hinze, Olga,Huchel, Ursula,Gerke, Thomas

, p. 539 - 553 (2017/01/25)

Five families of caged fragrance compounds that allow the storage and release of the following small volatile organic molecules are described: terpene hydrocarbons, aldehydes, ketones, Michael-type α,β-unsaturated enones, and carboxylic acids and esters. These caged molecules are released by photoexcitation via carbonyl-directed hydrogen-transfer processes and subsequent C-C bond cleavage (Norrish Type II) or by didenitrogenation of diazirines.

Page/Page column 22, (2014/12/09)

A compound of Formula (I) wherein R1 represents a C3 to C20 hydrocarbon group derived from a fragrant alcohol of formula R1OH or from a fragrant aryl aldehyde or ketone of Formula (II), wherein: R2 is, independently, hydrogen atom, hydroxyl group, acetoxy group, -O(C=O)CH(CH3), optionally substituted C1-C6 alkyl group or C1-C6 alkoxy group, wherein any two of R2 may form an optionally substituted 5 or 6 membered ring, and R1 represents a radical derived from a fragrant alcohol of formula R1OH or from a fragrant aldehyde or from a fragrant aryl aldehyde or ketone of formula (II). The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols or aldehydes.
