|  |  | Coumarin 120 Usage And Synthesis | 
 | Chemical Properties | Coumarin 120 is Light yellow beige powder |  | Uses | Coumarin 120 is widely used fluorophore, well-known for preparing fluorogenic substrates for cystine aminopeptidase and other hydrolases. Used as reference compound in enzyme assays. |  | Uses | suitable for determining polygalacturonase activity |  | Uses | λ max 354 nm in EthanolSuitable as laser dye and used as a fluorescent labeling reagent for trace determination of enzymes. |  | Definition | ChEBI: Coumarin 120 is a member of 7-aminocoumarins. It has a role as a fluorochrome. |  | General Description | 7-Amino-4-methylcoumarin (coumarin120) is an aminocoumarin laser dye that can emit laser in the range of 370-760 nm. It has three intermolecular hydrogen bonded structures with C-H···O and N-H····O. |  | Biochem/physiol Actions | 7-Amino-4-methylcoumarin is a coumarin derivative, which serves as a fluorescence reference standard to screen protease inhibitors. |  | storage | +4°C |  | Purification Methods | Dissolve it in 5% HCl, filter and basify with 2M ammonia. The precipitate is dried in a vacuum and recrystallised from dilute EtOH. It yields a blue solution and is light sensitive. [Sigler Synthesis 614 1980, Kanaoka et al.
