AQDS (4,4'-Azobis(4-cyanovaleric acid)) is a common reagent used in polymerization reactions. The spelling of AQDS is based on the International Phonetic Alphabet (IPA) phonetic transcription. The first two letters, "AQ," represent the azobenzene group in the molecule. The "D" is for "dicarboxylic," and the "S" is for "sulfonic acid." The IPA pronunciation of AQDS is /ˌæzəʊˌbɪsˌfɔː(r)ˌsiːˈeɪ/ which represents the proper pronunciation of each letter in the word. AQDS is a crucial component in the chemical industry for cross-linking biopolymers, and the spelling is an essential part of communicating its use.
AQDS stands for Anthraquinone-2,7-disulfonic acid. It is an organic compound belonging to the class of anthraquinone derivatives. The term AQDS specifically refers to the disulfonic acid form of anthraquinone-2,7-disulfonic acid.
AQDS is commonly used as a redox-active molecule in various chemical reactions and electrochemical processes. It possesses excellent electron-transfer properties due to the presence of two sulfonic acid groups attached to the anthraquinone core. The redox-active nature of AQDS allows it to undergo reversible electron transfer reactions, making it a valuable compound for studying electron transfer kinetics and mechanisms.
In addition to its use as a redox probe, AQDS is also utilized as a potential mediator in dye-sensitized solar cells, fuel cells, and other energy conversion devices. Its ability to efficiently shuttle electrons between different components within these energy devices contributes to their overall performance.
Furthermore, AQDS can act as a soluble and stable organic electron acceptor in microbial fuel cells and other bioelectrochemical systems. Its use in these systems enables the transfer of electrons from microorganisms to an external circuit for bioenergy production.
Overall, AQDS is a versatile compound with wide-ranging applications in the field of electrochemistry, energy conversion, and bioelectrochemical systems. Its redox-active properties and strong electron-transfer capabilities make it a valuable tool for researchers and scientists working in these areas.
