Acid-base (PH) indicator

BCECF is a pH-sensitive fluorescent dye and a cytosolic pH indicator. It can be used for detecting intracellular pH levels.

Pyranine (Solvent Green 7) is reported as a new class of fluorescent chemosensor for the Cu+ ion.

Neutral red is a vital dye, is used as an indicator and biological stain.

Phenol Red (Sulfonphthal) is a pH indicator, red dye, and diagnostic aid for measurement of renal function. It is used also for researches of the gastrointestinal and other systems.

Acid Yellow 36 (Metanil Yellow) is an azo dye and pH indicator, changing color from red at pH 1.2 to yellow at pH 2.3.

Xylenolblue (p-Xylenol Blue) is an acid-base indicator used as an intermediate in chemical synthesis.

Cresol Red sodium is a useful organic compound for research related to life sciences. The catalog number is T66428 and the CAS number is 62625-29-0.

3,6-diacetoxy Phthalonitrile is a fluorescent probe for monitoring intracellular pH by flow cytometry in living cells. It rapidly crosses cell membranes and is cleaved by cytosolic esterases to form the fluorescent pH indicator 2,3-dicyano-hydroquinone (DCH), which is excited at UV wavelengths. DCH can be excited at 351 nm, with pH-dependent emission in the range of 450-476 nm (pH 5.0-10.0) using a potassium-based buffer.
