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.

For use with Osteo-bed bone embedding kit. Solvent for removal of plastic from sections prior to rehydration and staining. Most histochemical and immunohistochemistry staining protocols require the removal of methyl methacrylate (MMA) and rehydration of mounted sections for improved stain penetration and greater contrast.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.

1,3-Dihydroxynaphthalene is a dye intermediate forming stable colors when applied with particular mordants and in mixtures with other oxidising dyes. This specific reagent is intended for the quantitative colorimetric determination of alduronic acids, such as glucuronic acid from urine. The mutagenicity of ozonation derivatives of 1,3-dihydroxynaphthalene against several Salmonella typhimurium strains has been studied.
