7-(7-Aminoheptanamido)heptanoic acid CAS 1308300-37-9

Description

The occurrence of 7-(7-Aminoheptanamido)heptanoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-(7-Aminoheptanamido)heptanoic acid (CAS 1308300-37-9) is a high-purity analytical reference standard with the molecular formula C14H28N2O3 and a molecular weight of 272.38 g/mol.

The molecular framework of 7-(7-Aminoheptanamido)heptanoic acid (C14H28N2O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
