closed-HMRG
- CAS No.: 7449-51-6
- Formula:C20H16N2O2
- Molecular Weight:316.35
InChIKey: ALPRHLCJLWIKCA-UHFFFAOYSA-N
SMILES: NC1=CC=C2C(OC3=CC(N)=CC=C3C24OCC5=C4C=CC=C5)=C1
Biological Activity: closed-HMRG is HMRG with closed spirocyclic structure. Ac-HMRG, an acetylated derivative of Hydroxymethyl rhodamine green, exists as a closed spirocyclic structure in aqueous solution at physiological pH, whereas HMRG itself takes an open nonspirocyclic structure. Ac-HMRG is colorless and nonfluorescent and HMRG is strongly fluorescent[1].
