Fea­tures

1. The flu­o­res­cence is strongest under alka­line con­di­tions, show­ing green fluorescence ;
2. Usu­al­ly used in aque­ous solu­tion (such as 40% aque­ous solution);
3. Rel­a­tive­ly high safe­ty, envi­ron­men­tal­ly friend­ly when used in small amounts.

Known Appli­ca­tion

1. Dyes and trac­ers
   Flu­o­res­cent trac­er :
   Com­mon­ly used to detect liq­uid flow path, leak­age loca­tion, ground­wa­ter flow direc­tion, water pipe leak­age, etc.
   Water pol­lu­tion track­ing :
   In the field of envi­ron­men­tal pro­tec­tion, it is used to track the dif­fu­sion path of pol­lu­tants in water bodies.
2. Bio­med­ical and ana­lyt­i­cal appli­ca­tions
   Cell stain­ing agent :
   Used as a flu­o­res­cent dye when observ­ing cells, tis­sues or bio­log­i­cal struc­tures under a micro­scope.
   Oph­thal­mo­log­i­cal exam­i­na­tion :
   Used for corneal stain­ing test to check corneal dam­age or for­eign mat­ter (such as used with a blue light slit lamp).
   Cap­il­lary elec­trophore­sis, elec­trophore­sis analy­sis :
   As a flu­o­res­cent label­ing reagent to improve detec­tion sensitivity.
3. Indus­tri­al detec­tion
   Pipeline detec­tion :
   Adding this dye to petro­chem­i­cal, refrig­er­a­tion, air con­di­tion­ing and oth­er sys­tems, and irra­di­at­ing with ultra­vi­o­let light can locate the leak point.
   CIP val­i­da­tion :
   In the phar­ma­ceu­ti­cal and food indus­tries, it is used to con­firm whether the clean­ing process is thorough.
