Properties and Uses of Trans-Cinnamic Acid CAS NO. 140-10-3


Properties and Uses of Trans-Cinnamic Acid CAS NO. 140-10-3


Cinnamic acid(CAS NO. 140-10-3) is a white crystalline compound with the formula C6H5CH=CHCOOH that is slightly soluble in water, and freely soluble in many organic solvents.

Cis- Cinnamic Acid & Trans-Cinnamic Acid




Cinnamic acid exists as trans and cis isomers, but the trans form is the one most often found in nature and is the article of commerce. It is obtained from cinnamon bark and balsam resins. It is synthesized by the Perkin reaction between Ac2O and PhCHO.

Production of Trans-Cinnamic Acid

1 - obtained from oil of cinnamon, or from balsams such as storax

2 - found in shea butter and is the best indication of its environmental history and post-extraction conditions

3 - prepared from cinnamaldehyde and benzal chloride or by the Knövenaegel–Hans condensation reaction

Uses of Trans-Cinnamic Acid

Trans-Cinnamic acid is very important because it is widely used in perfume, food, photographic, polymer and pharmaceutical industries.




1)   Flavors and fragrances

1.1 Used as a flavoring agent for bakery goods, confectionaries, beverages, and toothpaste.

1.2 Used to impart fragrance in air fresheners, soaps, and cosmetics.

1.3 Used as a blender in perfumes, particularly for floral fragrances.

1.4 Used in products where a spicy character is required such as in mouthwash and chewing gums.

2) The perfume industry

Trans-Cinnamic acid is involved making of the methyl, ethyl, and benzyl esters for the perfume industry.

3)Others

Cinnamic acid acts as a precursor to the sweetener aspartame due to enzyme-catalysed amination to phenylalanine. And it is also a type of self-inhibitor produced by fungal spores in order to prevent germination.

Applications of Trans-cinnamic Acid

Trans-cinnamic acid, also known as (2e)-3-phenyl-2-propenoic acid or (E)-cinnamate, is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Trans-cinnamic acid is a sweet, balsam, and honey tasting compound and can be found in a number of food items such as maitake, mustard spinach, common wheat, and barley, which makes trans-Cinnamic acid a potential biomarker for the consumption of these food products. Trans-cinnamic acid can be found primarily in saliva. Trans-cinnamic acid exists in all living species, ranging from bacteria to humans. Trans-cinnamic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Cinnamic acid is an organic compound with the formula C6H5CHCHCO2H. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants....

Fragrance or Flavor Odor Type Listing

Fragrance and flavor substances are comparatively strong-smelling organic compounds with characteristic, usually pleasant odors. The odors of single chemical compounds are extremely difficult to describe unequivocally. The odors of complex mixtures are often impossible to describe unless one of the components is so characteristic that it largely determines the odor or flavor of the composition. Although an objective classification is not possible, an odor can be described by adjectives such as flowery, fruity, woody, or hay-like, which relate the fragrances to natural or other known products with similar odors. Such as, Pure ethyl cinnamate has a fruity and balsamic odor. A few terms used to describe odors are listed below: Aldehydic odor note of the long-chain fatty aldehydes, e.g., fatty-sweaty, ironed laundry, seawater Animal(ic) typical notes from the animal kingdom, e.g., musk, castoreum, skatole, civet, ambergris Ba...

Which Method is Better to Repel Birds?

Birds can be friends of mankind and a symbol of beauty, but for growers, it might be a trouble. If it is not driven out in time, it will bring great losses. -      Manual Bird Repellent After seeing birds, drive them away manually,  paying particular attention to the early morning and evening periods (the harm is serious). Advantages:  No other additional costs. Disadvantages:  It is impossible for people to watch 24 hours. After all, they have to be busy with their own affairs. -  Reflective Tape to Repel Birds Pulling this kind of reflective ribbon in the orchard stimulates the eyes of birds through the reflected sunlight to achieve the effect of repelling birds. Advantages:  the method is simple and easy to implement, and does not require a large cost. Disadvantages:  The effect of repelling birds is more obvious under sunny conditions; after a long period of use, the effect will be greatly reduced when ...
