Description of o-Phthalaldehyde
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.

What is o-Phthalaldehyde?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is o-Phthalaldehyde which has developed particularly rapidly in recent years. Do you know about o-Phthalaldehyde ?
- The official answer：Phthalaldehyde, a light yellow crystal, sensitive to light and air, can be volatilized with water vapor. Soluble in water, ethanol, ether, and organic solvents, slightly soluble in petroleum ether. It is irritating. Mainly used in 1, chemical field analysis reagent: as amine alkaloids reagent, used in fluorometric determination of primary amines and peptide bond decomposers. 2、Organic synthesis: also pharmaceutical intermediates .3、Fluorescent reagent for pre-column HPLC separation of amino acid derivatives, flow cytometric measurement of thiol groups of proteins. Slightly hazardous to water, do not allow undiluted or large amounts of product to come into contact with groundwater, waterways, or sewage systems. Do not discharge material into the surrounding environment without government permission.
What’s the application of o-Phthalaldehyde?
It is a pharmaceutical intermediate, the latest topical and efficient safe antimicrobial disinfectant, used as sterilization and disinfection of endoscopic surgical instruments in hospitals, used in the synthesis of new anti-platelet aggregation drug indolebofen, and also as an analytical reagent in the field of chemistry. Uses yellow needle-like crystals, mainly used in medicine, dyestuff, etc. Amino acid derivatization reagent, fluorescence detection, the reaction can be completed in one minute, but the product is unstable and needs to be detected immediately. UsesMainly used in medicine, dyestuff, amino acid derivative reagent, etc. UsesReagent for amine alkaloids, used in fluorometric determination of primary amines and peptide bond decomposers. Organic synthesis. Reagent for amine alkaloids, used for the determination of primary amines and peptide bond decomposers by fluorometric method; suitable for pre-column derivatization of amino acids in high-performance liquid chromatography separation; used for measuring protein sulfhydryl groups by flow cytometry 1.
