o-Phthalaldehyde (CAS 643-79-8) can be widely used for precolumn derivatization of amino acids in HPLC separation or Capillary electrophoresis. For flow cytometric measurements of protein thiol groups. o-Phthalaldehyde is a high-level chemical disinfectant that is commonly used for disinfection of dental and medical instruments as an alternative to glutaraldehyde. Mainly used in medicine, dyestuff and so on. The product is a pharmaceutical intermediates, the latest topical efficient and safe anti-bacterial disinfectant, can be used for the synthesis of new anti-platelet aggregation drugs indole Bofen, but also the field of chemistry analysis reagents. o-Phthalaldehyde is a compound that reacts with primary amines to produce a product that emits a highly fluorescent blue colour. o-Phthalaldehyde is used for the quick visualization of histamine, characterized by the appearance of a yellow stain. Phthaldialdehyde is used as a fluorescent reagent for checking the assay of amines present in proteins, peptides by capillary electrophoresis and chromatography.
