72707-66-5 Usage


2-(Bromomethyl)acrylic Acid, also known as 2-bromoacrylic acid, is an organic compound with the chemical formula C4H5BrO2. It is a colorless to pale yellow liquid with a pungent odor. 2-(BROMOMETHYL)ACRYLIC ACID is characterized by its bromine atom attached to the methylene group in the acrylic acid structure, which makes it a versatile building block in organic synthesis.


Used in Pharmaceutical Industry:
2-(Bromomethyl)acrylic Acid is used as a chemical intermediate for the synthesis of various complex organic compounds and pharmaceuticals. Its unique structure allows it to be a key component in the development of new drugs and medicines.
Used in Synthesis of Methotrexate Analogues:
2-(Bromomethyl)acrylic Acid is used as a reactant in the synthesis of methotrexate analogues. It reacts with aldehydes and ketones to form α-methylene-butyrolactones, which are important intermediates in the production of these analogues. Methotrexate is a widely used drug for the treatment of various cancers and autoimmune diseases, and its analogues may offer improved efficacy or reduced side effects.

Check Digit Verification of cas no

The CAS Registry Mumber 72707-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,0 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72707-66:
135 % 10 = 5
So 72707-66-5 is a valid CAS Registry Number.

Artificial [FeFe]-hydrogenase: On resin modification of an amino acid to anchor a hexacarbonyldiiron cluster in a peptide framework

Roy, Souvik,Shinde, Sandip,Hamilton, G. Alexander,Hartnett, Hilairy E.,Jones, Anne K.

experimental part, p. 1050 - 1055 (2011/06/10)

A general method for immobilization of synthetic analogues of the [FeFe]-hydrogenase in designed peptides via on resin modification of an amino acid side chain with a dithiol functional group is described. Utilizing a unique amine side chain as anchor, the dithiol unit is coupled to the peptide via formation of an amide. This dithiol unit precisely positions the two required sulfur atoms for the formation of a [(μ-SRS){Fe-(CO)3} 2] cluster on reaction with [Fe3(CO)12]. UV/Vis and FTIR spectroscopy demonstrate formation of the desired complex.
