Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Chloroethyl)-3-(2,4-dimethylphenyl)urea.
1-(2-Chloroethyl)-3-(2,4-dimethylphenyl)urea (CAS 162376-66-1), molecular formula C11H15ClN2O and molecular weight 226.70 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Chloroethyl)-3-(2,4-dimethylphenyl)urea (C11H15ClN2O) 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, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(2-Chloroethyl)-3-(2,4-dimethylphenyl)urea meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
