Chemical Structure
Description
1-(3-Chloro-4-methylphenyl)-3-(pyrimidin-2-yl)urea (CAS 64699-76-9) is a high-purity analytical reference standard with the molecular formula C12H11ClN4O and a molecular weight of 262.69 g/mol.
1-(3-Chloro-4-methylphenyl)-3-(pyrimidin-2-yl)urea (C12H11ClN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(3-Chloro-4-methylphenyl)-3-(pyrimidin-2-yl)urea 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.
