Description
Cysteic acid, also known as 3-sulfoalanine, is an amino sulfonic acid that is the sulfonic acid analogue of cysteine. It possesses unique chemical properties due to the presence of a sulfonic acid group, making it a versatile compound with potential applications in various fields.
Uses
Used in Chemical Synthesis:
Cysteic acid is used as a building block in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and other specialty chemicals. Its unique sulfonic acid group allows for the formation of stable derivatives and facilitates various chemical reactions.
Used in Biochemistry and Molecular Biology:
Cysteic acid can be used as a modifier of proteins and peptides, introducing sulfonic acid groups that can alter their properties and functions. This can be useful in studying protein structure, function, and interactions, as well as in the development of novel bioactive molecules.
Used in Environmental Applications:
Due to its acidic and hydrophilic nature, cysteic acid can be employed in water treatment processes, such as the removal of heavy metals and other pollutants from wastewater. Its ability to form complexes with various metal ions makes it a promising candidate for environmental remediation.
Used in Material Science:
Cysteic acid can be incorporated into the design of new materials with specific properties, such as ion-exchange resins, catalysts, and sensors. Its sulfonic acid group can provide sites for ion binding and facilitate electron transfer, making it a valuable component in the development of advanced materials.
Purification Methods
Likely impurities are cystine and oxides of cysteine. Crystallise the acid from water by adding 2 volumes of EtOH. It crystallises from H2O as the monohydrate. When recrystallised from aqueous MeOH it has m 264-266o, and the anhydrous acid has m ~260o(dec).

Check Digit Verification of cas no
The CAS Registry Mumber 13100-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13100-82:
(7*1)+(6*3)+(5*1)+(4*0)+(3*0)+(2*8)+(1*2)=48
48 % 10 = 8
So 13100-82-8 is a valid CAS Registry Number.

GLUCAGON ANALOGS EXHIBITING ENHANCED SOLUBILITY IN PHYSIOLOGICAL pH BUFFERS
-
, (2010/08/07)
Modified glucagon peptides are disclosed having improved solubility while retaining glucagon agonist activity. The glycogen peptides have been modified by substitution of native amino acids with, and/or addition of, charged amino acids to the carboxy terminus of the peptide. The modified glucagon agonists can be further modified by pegylation, or the addition of a carboxy terminal peptide selected from the group consisting of SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 23, or both to further enhance the solubility of the glucagon agonist analogs.
