Description
TRANS-2-METHYL-2-BUTENAL, also known as tiglic aldehyde, is a clear colorless to yellow liquid with a penetrating, powerful green ethereal odor. It is one of the major volatile constituents found in coriander and olive oil and can be prepared by the condensation of acetaldehyde and propionaldehyde.
Uses
Used in Chemical Synthesis:
TRANS-2-METHYL-2-BUTENAL is used as a starting reagent in the synthesis of various compounds, such as alkyl-branched tetraene hydrocarbons, pheromone components for dried fruit beetles, and volatile constituents of defensive secretions in certain insects.
Used in Fragrance Industry:
TRANS-2-METHYL-2-BUTENAL is used as a fragrance ingredient due to its powerful green ethereal odor, contributing to the characteristic scent of coriander and olive oil.
Used in Pharmaceutical Industry:
TRANS-2-METHYL-2-BUTENAL was used in the concise total synthesis of 7-demethylpiericidin A1, indicating its potential application in the development of pharmaceutical compounds.
Used in Insect Pheromones:
TRANS-2-METHYL-2-BUTENAL is used as a pheromone component for dried fruit beetles, playing a role in attracting and communicating between these insects.
Used in Defensive Secretions of Insects:
TRANS-2-METHYL-2-BUTENAL is a volatile constituent found in the defensive secretions of Leiobunum nigripalpi, an insect species, where it may serve as a protective mechanism against predators.
Check Digit Verification of cas no
The CAS Registry Mumber 497-03-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 497-03:
(5*4)+(4*9)+(3*7)+(2*0)+(1*3)=80
80 % 10 = 0
So 497-03-0 is a valid CAS Registry Number.

Rhodium-catalyzed hydroformylation of alkynes employing a self-assembling ligand system
Agabekov, Vladislav,Seiche, Wolfgang,Breit, Bernhard
, p. 2418 - 2422 (2013/07/11)
Hydroformylation of alkynes is an underdeveloped atom-economic and redox-neutral method to prepare enals. Applying a new electron poor self-assembling ligand system provides the first general rhodium-catalyst for the chemo- and stereoselective hydroformylation of dialkyl- as well as diaryl-substituted alkynes to furnish enals in excellent chemo- and stereoselectivity.
