Safranine
Definition:
(n.) An orange-red nitrogenous dyestuff produced artificially by oxidizing certain aniline derivatives, and used in dyeing silk and wool; also, any one of the series of which safranine proper is the type.
Example Sentences:

(5) Astra blue (AB) safranine stained highly significantly more mast cells than did toluidine blue.
(6) There was a profound loss of safranin-O stainability in the nucleus pulposus, annulus fibrosus and cartilagenous endplate.
