C6H6N2O2S2

C6H6N2O2S2 is the molecular formula for several chemical compounds. One such compound is thiouracil, a heterocyclic organic compound. Thiouracil is a derivative of uracil, a pyrimidine base, where an oxygen atom is replaced by a sulfur atom. It is known for its role as an antithyroid drug, used to treat hyperthyroidism by inhibiting the synthesis of thyroid hormones. Thiouracil exists in two tautomeric forms, a thione form and a thiol form, with the thione form being more stable.

Another compound with the formula C6H6N2O2S2 is cyclic disulfide, such as cystine. Cystine is a dimer of the amino acid cysteine, linked by a disulfide bond. This disulfide bond plays a crucial role in the tertiary structure of proteins, contributing to their stability and function. Cystine is important in biological systems and is found in various proteins, including keratin, a structural protein in hair and nails. The arrangement of atoms and the presence of sulfur atoms are key characteristics of molecules represented by this formula.
