O-Phthalaldehyde or ortho-phthalaldehyde (OPA) is the chemical compound with the formula C6H4(CHO)2. Often abbreviated OPA, the molecule is a dialdehyde, consisting of two formyl (CHO) groups attached to adjacent carbon centres on a benzene ring. This pale yellow solid is a building block in the synthesis of heterocyclic compounds and a reagent in the analysis of amino acids. OPA dissolves in water solution at pH < 11.5. Its solutions degrade upon UV illumination and exposure to air. The product is a pharmaceutical intermediates, latest topical safe and efficient disinfectant as hospital endoscopic surgery instrument sterilization, for the synthesis of a new anti platelet aggregation drug indole Bofen, but also the field of chemical analytical reagent. Yellow needle crystal, mainly used in medicine, dyes, etc.. Amino acid derivatization reagent, fluorescence detection, the reaction in a minute, but the product is not stable, need to immediately detect. Mainly used in medicine, dyes, amino acidderivatives, etc..
Yellow or light yellow crystalline
