Chemical Structure

Aspartic acid, N-(3-carboxy-1-oxo-3-sulfopropyl)-N-octadecen-1-yl-, sodium salt (1:4) CAS 81869-18-3 chemical structure

Description

The occurrence of Aspartic acid, N-(3-carboxy-1-oxo-3-sulfopropyl)-N-octadecen-1-yl-, sodium salt (1:4) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Aspartic acid, N-(3-carboxy-1-oxo-3-sulfopropyl)-N-octadecen-1-yl-, sodium salt (1:4) (CAS 81869-18-3), molecular formula C26H41NO10SNa and molecular weight 582.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Aspartic acid, N-(3-carboxy-1-oxo-3-sulfopropyl)-N-octadecen-1-yl-, sodium salt (1:4) (C26H41NO10SNa) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
