Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-[3-(Difluoromethoxy)phenyl]-3-[2-methyl-6-(propan-2-yl)phenyl]thiourea (CAS 1858255-85-2) is a high-purity analytical reference standard with the molecular formula C18H20F2N2OS and a molecular weight of 350.43 g/mol.
Structurally, 1-[3-(Difluoromethoxy)phenyl]-3-[2-methyl-6-(propan-2-yl)phenyl]thiourea (C18H20F2N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 350.43 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
