Phthalylsulfathiazole, chemically known as 2-[[4-(2-thiazolylsulfamoyl)phenyl]carbamoyl]benzoic acid, is a complex organic molecule that forms the basis of its therapeutic efficacy. Its molecular formula is C17H13N3O5S2, and it possesses a molecular weight of approximately 403.43 g/mol. The structure features a sulfonamide group, which is characteristic of its class, linked to a phthalic acid derivative and a thiazole ring. This intricate arrangement of functional groups dictates its interaction with biological targets, particularly enzymes within bacterial metabolic pathways.

As a Phthalylsulfathiazole chemical supplier, understanding these properties is paramount. The compound is typically supplied as a white or off-white crystalline powder. Its physical state as a solid and its limited solubility in water but better solubility in certain organic solvents, like DMSO, are critical considerations for formulation and experimental setup. The melting point of Phthalylsulfathiazole is notably high, often reported as above 240°C, indicating a stable crystalline structure. For researchers seeking to order Phthalylsulfathiazole, awareness of these physical characteristics is essential for proper handling, storage, and dissolution, ensuring the compound's integrity and performance.

The precise arrangement of atoms within the Phthalylsulfathiazole molecule, including the electron-withdrawing nature of the sulfur and nitrogen atoms, contributes to its reactivity and its ability to bind to specific enzymatic sites. This molecular architecture is what enables it to act as a PABA antagonist. When sourced from a reliable Phthalylsulfathiazole manufacturer like NINGBO INNO PHARMCHEM CO.,LTD., users can be assured of the compound's accurate chemical structure and purity, which are vital for reproducible scientific results. The Phthalylsulfathiazole formula and its associated CAS number (85-73-4) are standard identifiers used globally to ensure product specificity.
