Chemical Structure

1,7-Diaminoheptane CAS 646-19-5 chemical structure

Description

The occurrence of 1,7-Diaminoheptane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,7-Diaminoheptane (CAS 646-19-5) is a high-purity analytical reference standard with the molecular formula C7H18N2 and a molecular weight of 130.23 g/mol.

The molecular framework of 1,7-Diaminoheptane (C7H18N2) 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.

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.
