SDS of cas: 25150-27-0. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 6,7-Dichlorobenzo[d]thiazol-2-amine, is researched, Molecular C7H4Cl2N2S, CAS is 25150-27-0, about Synthesis of some 4H-pyrimido[2,1-b]benzothiazol-4-ones.
A series of 8-substituted and 7,8-disubstituted-4-oxo-3-(4H-pyrimido[2,1-b]benzothiazole)carboxylic acids (I) and esters including a 9-aza analog were synthesized from substituted 2-aminobenzothiazoles and di-Et ethoxymethylenemalonate. No significant antiparasitic activity was detected.
