Chemical Structure

<I>N</I>,<I>N</I>,<I>N</I>′,<I>N</I>′-tetramethyl-1,4-butanediamine CAS 111-51-3 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

<I>N</I>,<I>N</I>,<I>N</I>′,<I>N</I>′-tetramethyl-1,4-butanediamine (CAS 111-51-3), molecular formula C8H20N2 and molecular weight 144.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of <I>N</I>,<I>N</I>,<I>N</I>′,<I>N</I>′-tetramethyl-1,4-butanediamine (C8H20N2) is characterized by an organic framework. 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. 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.
