5-Isoquinolinesulfonic Acid (CAS: 27655-40-9) was used in the synthesis of conjugates of oligoarginine peptides. 5-Isoquinolinesulfonic Acid is an important pharmaceutical intermediate. It can be used to produce 5-Isoquinolinesulfonyl Chloride Hydrochloride. As an important intermediate of Fasudil Hydrochloride, how to synthesize 5-substituted isoquinoline-5-sulfonic acid in a directional manner without producing isomeric by-products has become a research hotspot for many pharmaceutical and chemical workers.
