Chemical Structure
Description
As a certified reference material (CRM), N2,N2-Dimethylpyridine-2,5-diamine hydrochloride 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.
N2,N2-Dimethylpyridine-2,5-diamine hydrochloride (CAS 119151-81-4), molecular formula C7H11N3HCl and molecular weight 173.64 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H11N3HCl, N2,N2-Dimethylpyridine-2,5-diamine hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
