Task: Please create a description for a molecule based on its representation.
Molecule SMILES: Cc1ccc2nc(-c3ccc4nc(-c5ccc(N)cc5)sc4c3)sc2c1S(=O)(=O)O
Constraint: Answer the question with full sentences.
Result: The molecule is a member of the class of benzothiazoles that is 2,6'-bi-1,3-benzothiazole substituted at positions 2' 6 and 7 by 4-aminophenyl, methyl and sulfo groups respectively. The monosodium salt is the biological dye 'primuline'. It has a role as a fluorochrome and a histological dye. It is a member of benzothiazoles, a ring assembly, a substituted aniline and an arenesulfonic acid. It is a conjugate acid of a 2'-(4-aminophenyl)-6-methyl[2,6'-bi-1,3-benzothiazole]-7-sulfonate.
