Hazard Information | Back Directory | [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. Chem Pharm Bull Jpn 30 1485 1982, Beilstein 18/11 V 445.] |
