O-Methylisourea hemisulfate

O-Methylisourea hemisulfate

O-Methylisourea Hemisulfate (CAS 52328-05-9) is the hemisulfate salt of O-methylisourea, a guanidinating reagent widely used for the chemical conversion of lysine residues to homoarginine in proteins and peptides. Structurally, O-Methylisourea Hemisulfate consists of a methyl isourea cation (C₂H₆N₂O⁺) associated with a half-equivalent of sulfate anion, forming the hemisulfate salt. The O-methylisourea molecule features a carbamimidic acid methyl ester structure: a central carbon atom bonded to an amino group, an imino nitrogen, and a methoxy group.
1H-1,2,4-Triazole-3-thiol

1H-1,2,4-Triazole-3-thiol

1H-1,2,4-Triazole-3-thiol (3-Mercapto-1,2,4-triazole, CAS 3179-31-5) is a heterocyclic compound featuring a five-membered 1,2,4-triazole ring with a thiol (mercapto) substituent at the 3-position. The molecule exists in tautomeric equilibrium between the thiol (-SH) and thione (=S) forms, with the thione tautomer (1,2-dihydro-3H-1,2,4-triazole-3-thione) being the predominant form in the solid state.
7-Dehydrocholesterol

7-Dehydrocholesterol

7-Dehydrocholesterol (Provitamin D₃, CAS 434-16-2) is a naturally occurring sterol and the immediate biosynthetic precursor to vitamin D₃ (cholecalciferol). Structurally, 7-Dehydrocholesterol is a cholesterol derivative differing from cholesterol by the presence of an additional double bond at the C7 position of the B-ring of the steroid nucleus, forming a conjugated diene system between C5 and C7.
2-Methyl-2-thiopseudourea sulfate

2-Methyl-2-thiopseudourea sulfate

2-Methyl-2-thiopseudourea Sulfate (S-Methylisothiourea sulfate, CAS 867-44-7) is a sulfur-containing guanidino compound and a potent inhibitor of nitric oxide synthase (NOS). Structurally, 2-Methyl-2-thiopseudourea Sulfate consists of a methyl isothiourea cation (C₂H₆N₂S⁺) associated with a sulfate anion, existing as the hemisulfate salt with a 2:1 stoichiometry (two methylisothiourea cations per sulfate).
3-nitro-4-(((tetrahydro-2H-pyran-4-yl)methyl)amino)-benzenesulfonamide

3-nitro-4-(((tetrahydro-2H-pyran-4-yl)methyl)amino)-benzenesulfonamide

3-nitro-4-(((tetrahydro-2H-pyran-4-yl)methyl)amino)-benzenesulfonamide (CAS 1228779-96-1) is a key pharmaceutical intermediate featuring a benzene sulfonamide core with strategically positioned functional groups. The molecule consists of a benzenesulfonamide ring substituted with a nitro group at the 3-position and an amino group at the 4-position, which is further substituted with a tetrahydro-2H-pyran-4-ylmethyl moiety.
1-((4'-chloro-5,5-dimethyl-3,4, 5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride

1-((4'-chloro-5,5-dimethyl-3,4, 5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride

1-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride (CAS 1628047-87-9) is a key pharmaceutical intermediate featuring a complex bicyclic structure.
