2409-87-2 Usage
General Description
2,4-Pentadienoic acid, methyl ester, (2E)-, also known as methyl sorbate, is a chemical compound commonly used as a food and beverage preservative due to its antimicrobial and antifungal properties. It is often added to products such as soft drinks, fruit juices, and alcoholic beverages to extend their shelf life and prevent spoilage. Methyl sorbate is also used in the production of fragrances and perfumes, as well as in the synthesis of other chemicals. It is a colorless liquid with a fruity odor and is considered safe for use in food and cosmetic products when used in accordance with regulations and guidelines. However, it should be handled and stored appropriately to prevent exposure to high temperatures and open flames, as it may release harmful fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 2409-87-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2409-87:
(6*2)+(5*4)+(4*0)+(3*9)+(2*8)+(1*7)=82
82 % 10 = 2
So 2409-87-2 is a valid CAS Registry Number.

Lithium/Ammonia Reductions of 2-Thiophenecarboxylic Acids
Blenderman, Walter G.,Joullie, Madeleine M.,Preti, George
, p. 3206 - 3213 (2007/10/02)
Lithium/ammonia reductions of 2-thiophenecarboxylic acids (1) in the absence of a proton source afforded mixtures of products.In the presence of methanol acyclic mercapto carboxylic acids (4) were the major products.Ring closure of 4 to the corresponding thiolactones (12) showed the double bonds in 4 to be of cis geometry.Attempts were made to prepare Z olefinic compounds derived from these mercapto carboxylic acids.Lithium 2-thiophenecarboxylate salts (2) afforded good yields of the corresponding 2,5-dihydro-2-thiophenecarboxylic acids (3).The presence of substituents on the ring and the ratio of metal to acid were significant factors in determining the nature of this products.A mechanism is proposed to explain the products observed.
