Chemical Structure

m-dPEG<SUP>®</SUP><SUB>12</SUB>-Lipoamide CAS 1334172-68-7 chemical structure

Description

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

m-dPEG<SUP>®</SUP><SUB>12</SUB>-Lipoamide (CAS 1334172-68-7), molecular formula C33H65NO13S2 and molecular weight 748.00 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-dPEG<SUP>®</SUP><SUB>12</SUB>-Lipoamide is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 748.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
