Chemical Structure
Description
1-(2-Hydroxyethyl)-1-methyl-3-phenylurea (CAS 36097-31-1) is a high-purity analytical reference standard with the molecular formula C10H14N2O2 and a molecular weight of 194.23 g/mol.
1-(2-Hydroxyethyl)-1-methyl-3-phenylurea (C10H14N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(2-Hydroxyethyl)-1-methyl-3-phenylurea 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.
