4.4 Specification

  Ferrocenecarboxylic acid , with CAS Registry Number 1271-42-7, its Synonyms are Carboxyferrocene ; Ferrocene, carboxy- (9CI) ; Ferroncene monocarboxylic acid . And Its IUPAC Name is Cyclopenta-1,3-diene; cyclopenta-2,4-diene-1-carboxylic acid; iron(2+) , and its Molecular Formula is C11H10FeO2. Besides, Ferrocenecarboxylic acid is dark brown powder and storage in Flammables area. It is stable and incompatible with strong oxidizing agents. In addition, Ferrocenecarboxylic acid belongs to Product Categories such as Aromatic Carboxylic Acids, Amides, Anilides, Anhydrides & Salts; Ferrocene series; Piperazine derivates. 

  Studies show that Polyacrylamide is used to fix catalase, uricase and Ferrocenecarboxylic acid on a working electrode, and Ferrocenecarboxylic acid modify carbon paste electrode (FCMCPE) in aqueous media using cyclic voltammetry and double step potential chronoamperometry. Furthermore, Ferrocenecarboxylic acid is irritating to eyes, respiratory system and skin, so we should wear suitable gloves and eye/face protection in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. In addition to this, it is also harmful if swallowed.
