Fluka
5-Aminofluorescein
p.a., for fluorescence, ≥90% (HPLC)
| Synonym: | Fluoresceinamine isomer I |
| CAS Number: | 3326-34-9 |
| Linear Formula: | C20H13NO5 |
| Molecular Weight: | 347.32 |

Description
| Application | The two isomers are produced by the usual synthesis. Most publications imply they are interchangeable when used for the preparation of the isothiocyanate for fluorescent antibody work. In fact, most commercial preparations are not even labeled as to whether or not they are mixtures. |
| Other Notes | All known glycosaminoglycuronans react with this fluorescein derivative to yield fluorescent derivatives1 |
| Note: Do not confuse with fluorescamine. |
