Chemical Structure

m-dPEG<SUP>®</SUP><SUB>8</SUB>-Lipoamide CAS 1334172-67-6 chemical structure

Description

CATO manufactures m-dPEG<SUP>®</SUP><SUB>8</SUB>-Lipoamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

m-dPEG<SUP>®</SUP><SUB>8</SUB>-Lipoamide (CAS 1334172-67-6) is a high-purity analytical reference standard with the molecular formula C25H49NO9S2 and a molecular weight of 571.79 g/mol.

The molecular framework of m-dPEG<SUP>®</SUP><SUB>8</SUB>-Lipoamide (C25H49NO9S2) is characterized by an amide group, a sulfone 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.
