Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N1,N1-Diethyl-3-methylbenzene-1,4-diamine dihydrochloride.
N1,N1-Diethyl-3-methylbenzene-1,4-diamine dihydrochloride (CAS 54749-07-4), molecular formula C11H18N2HCl and molecular weight 214.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N1,N1-Diethyl-3-methylbenzene-1,4-diamine dihydrochloride (C11H18N2HCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N1,N1-Diethyl-3-methylbenzene-1,4-diamine dihydrochloride 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.
