Sulforhodamine 101 (Texas Red) sulfonyl chloride



Product Description

Sulforhodamine 101 sulfonyl chloride (also called Texas Red sulfonyl chloride) is a popular long wavelength amine-reactive rhodamine dye. Because the dye is quite unstable in water, reactions with amines in an aqueous solution must be carried out at low temperature and at pH 8.5. Biotium developed sulforhodamine 101-PEO2 SE as a superior alternative to sulforhodamine 101 sulfonyl chloride because the dye has a water-soluble spacer group and is also much more stable.
