The present disclosure is related to the synthesis and applications of a benzo[a]phenoxazine. It displays good photophysical properties, such as high molar extinction coefficient, good fluorescence quantum yield and solubility in water. The present invention also refers to the use of the fluorochromophore simultaneously as fixative and label in a composition for cytology, preferably mucous cells, like cells from the oral cavity and, cells from exo and endocervix. This composition is suitable for medical use, such as in neoplasic detection, preferably, cervix and oral cavity cancers.

Ultrasound irradiation was used for the first time towards the synthesis of new Nile Blue related benzo[a]phenoxazinium chlorides possessing isopentylamino, (2-cyclohexylethyl)amino and phenethylamino groups at 5-position of the heterocyclic system. The efficacy of sonochemistry was investigated with some of our earlier reported synthesis of benzo[a]phenoxazinium chlorides. This newer protocol proved competent in terms of reaction times and enhanced yields. Photophysical studies carried out in ethanol, water and simulated physiological conditions, revealed that emission maxima occurred in the range 644-656 nm, with high fluorescent quantum yields. Other attractive feature exhibited by these materials includes good thermal stability. These properties might be useful in the development of fluorescent probes for biotechnology.
