Chemical Structure
Description
As a certified reference material (CRM), 1-N-(4-methylphenyl)benzene-1,2-diamine 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.
CATO supplies 1-N-(4-methylphenyl)benzene-1,2-diamine (CAS 91806-09-6), a certified reference material (molecular formula C13H14N2HCl, MW 234.73 g/mol) for analytical method development and quality control.
Structurally, 1-N-(4-methylphenyl)benzene-1,2-diamine (C13H14N2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 234.73 g/mol, it falls into the medium-molecular-weight range. 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.
