Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 22440-93-3 N,N,N',N'-Tetramethylbenzene-1,3-diamine 1,3-Benzenediamine, N1,N1,N3,N3-tetramethyl- 1,3-Benzenediamine, N,N,N',N'-tetramethyl- EINECS 244-998-8 N,N,N',N'-Tetramethyl-m-phenylenediamine.

22440-93-3 N,N,N',N'-Tetramethylbenzene-1,3-diamine 1,3-Benzenediamine, N1,N1,N3,N3-tetramethyl- 1,3-Benzenediamine, N,N,N',N'-tetramethyl- EINECS 244-998-8 N,N,N',N'-Tetramethyl-m-phenylenediamine (CAS 22440-93-3) is a high-purity analytical reference standard with the molecular formula C10H22N2 and a molecular weight of 170.30 g/mol.

The molecular framework of 22440-93-3 N,N,N',N'-Tetramethylbenzene-1,3-diamine 1,3-Benzenediamine, N1,N1,N3,N3-tetramethyl- 1,3-Benzenediamine, N,N,N',N'-tetramethyl- EINECS 244-998-8 N,N,N',N'-Tetramethyl-m-phenylenediamine (C10H22N2) is characterized by an organic framework. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 22440-93-3 N,N,N',N'-Tetramethylbenzene-1,3-diamine 1,3-Benzenediamine, N1,N1,N3,N3-tetramethyl- 1,3-Benzenediamine, N,N,N',N'-tetramethyl- EINECS 244-998-8 N,N,N',N'-Tetramethyl-m-phenylenediamine 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.
