Chemical Structure
Description
1-(4-Fluoro-3-methylphenyl)-3-methylthiourea (CAS 866150-17-6), molecular formula C9H11FN2S and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Fluoro-3-methylphenyl)-3-methylthiourea (C9H11FN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-(4-Fluoro-3-methylphenyl)-3-methylthiourea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
