Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 318.80 g/mol gives 3-(4-Chlorophenyl)-1-methyl-1-(2-methyl-4,5,6,7-tetrahydro-2H-indazol-3-yl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-Chlorophenyl)-1-methyl-1-(2-methyl-4,5,6,7-tetrahydro-2H-indazol-3-yl)urea (CAS 219865-31-3), molecular formula C16H19ClN4O and molecular weight 318.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chlorophenyl)-1-methyl-1-(2-methyl-4,5,6,7-tetrahydro-2H-indazol-3-yl)urea (C16H19ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 3-(4-Chlorophenyl)-1-methyl-1-(2-methyl-4,5,6,7-tetrahydro-2H-indazol-3-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.
