Sodium azodisalicylate, Azodisal disodium, Olsalazine sodium, CJ-91B, di-5-ASA, ADS, Dipentum
奥沙拉嗪钠 奥沙拉嗪 Chemical Name: 4,4'-Dihydroxyazobenzene-3,3'-dicarboxylic acid disodium salt; 3,3'-Azobis(6-hydroxybenzoic acid) disodium salt; 5,5'-Azodisalycilic acid disodium salt
CAS No. 6054-98-4, 15722-48-2 (free acid)
项目整合开发状态: Launched-1985
项目研究机构: Pfizer (Originator), Celltech (Licensee)
合成路线:The diazotation of methyl-5-amino-2-hydroxybenzoate (I) with NaNO2 and HCl gives the cor responding diazonium salt (II),which is coupled with methyl 2-hydroxybenzoate (III) to afford the corresponding azobenzene (IV).Finally,this compound is hydrolyzed with boiling 1N NaOH.
