5,8-Dibromoisoquinoline is a achromatic clear or liquid. Melting point 26.48 ℃, 242.2℃boiling point ( 99.1kPa ), the about body of 1.09101 ( 30/4 ℃), refractive basis 1.62078 ( 30 ℃), beam is 107 ℃. With a array of amoebic solvents miscible, acrid in adulterated acid. With a able acrid absorbent, quinoline. Similar to anise oil and methyl phenyl ether smell. With the beef can be volatile. Afterwards storage, the blush yellow. PKa=5.4, acrid hardly stronger than quinoline, can become a alkali and acid: its hydrochloride, melting point 209 ℃, melting point 223 ℃picrate. N can action acylation and alkylation reaction, its melting point is 159 ℃methiodide. Electrophilic barter occurs in the 5 or 8 bits. Nucleophilic barter occurs in 1. Susceptible to blaze and abridgement reaction. Found in atramentous tar, authoritative accessible than Zeller – Na Pierre Lars Ki amalgam or Pomerantz – Selfridge reaction. Containing isoquinoline ring some important alkaloids. Can accomplish drugs and insecticide, blaze can be fabricated afterwards pyridine carboxylic acid, its acquired can be acclimated in the accomplish of blush blur and dye. Acclimated as average and constructed drugs, dyes, pesticides, gas chromatography anchored liquid. Quinoline can accomplish agitator acylation acknowledgment and polymerization acknowledgment of olefins, acrid phenolic adhesive abating agent, metal.

5,8-Dibromoisoquinoline is acrid permanganate oxidation, two rings can be degraded, acquired is a admixture of pyridine -3,4- two formic acerbic and the adjoining benzene two formic acid. While in aloof average with potassium permanganate blaze of benzene ring, not alone generation, adjoining benzene two formyl imine. Of substituents on the benzene ring can access the blaze acknowledgment results. With peracetic acerbic blaze of isoquinoline, to isoquinoline N- oxide. Isoquinoline can be catalytic hydrogenation, hydride reagents or metal reduction; aswell can apprehend the careful restore absolutely or partially bargain isoquinoline pyridine ring or ring. Catalytic hydrogenation of the artefact is abundantly afflicted by acerb acknowledgment medium: in acerb acid, pyridine ring careful abridgement of 1,2,3,4- four hydrogen isoquinoline; and in concentrated hydrochloric acid, benzene by careful abridgement of 5,6,7,8- four hydrogen isoquinoline, added abridgement of a admixture of CIS and auto ten hydrogen isoquinoline is generated. Vapour is acid to the nose, throat. Afterwards assimilation could cause headache, dizziness, nausea. Acid to eyes, skin. Articulate dispatch of the articulate and stomach. The air absorption beat the standard, should abrasion gas masks. Emergency accomplishment or escape, acclaim cutting independent breath apparatus.
