It may be used to prepare porphyrin based matrices for the detection of water soluble vitamins by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. It may be used to prepare 5,10,15,20-tetrakis (4-polyethyleneoxy)phenyl)) porphyrin. Nanoporous silica inserted with 2H-OHTPP imparts gas sensitivity, and it could be useful to detect NO2 by surface plasmon resonance.

Acridine orange is a metachromatic dye which can stain DNA, RNA and acid glycosaminoglycans. At low concentrations, it intercalates into DNA and precipitates RNA. However, at high concentrations it denatures and precipitates both RNA and DNA. Acridine orange is also used to analyse autophagy. It enters into acidic organelles in a pH-dependent manner. At neutral pH, acridine orange gives a green fluorescence and in acidic conditions, it accumulates in acidic organelles giving a bright red fluorescence.

Eosin Y, also known as Eosin yellowish is a widely used xanthene dye. It is a counterstain that is used to distinguish between various connective tissue fibers and matrices, and the cytoplasm of different types of cells. Eosin in combination with hematoxylin is useful to demonstrate the general histological architecture of a tissue.

Bromocresol Green (BCG), also known as bromcresol green, is a synthetic, anionic, triphenylmethane dye belonging to the phthalein and sulphonphthalein dyes group. It is commonly used as a pH indicator as it changes colour from yellow to blue-green at pH 3,8 to 5,4. The monosodium salt of bromocresol green is highly ionisable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.
