MAL-dPEG<SUP>®</SUP><SUB>4</SUB>-(m-dPEG<SUP>®</SUP><SUB>12</SUB>)<SUB>3</SUB> CAS 1334178-05-0 chemical structure

Description

The occurrence of MAL-dPEG<SUP>®</SUP><SUB>4</SUB>-(m-dPEG<SUP>®</SUP><SUB>12</SUB>)<SUB>3</SUB> is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

MAL-dPEG<SUP>®</SUP><SUB>4</SUB>-(m-dPEG<SUP>®</SUP><SUB>12</SUB>)<SUB>3</SUB> (CAS 1334178-05-0), molecular formula C106H202N6O50 and molecular weight 2360.75 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, MAL-dPEG<SUP>®</SUP><SUB>4</SUB>-(m-dPEG<SUP>®</SUP><SUB>12</SUB>)<SUB>3</SUB> (C106H202N6O50) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 2360.75 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures MAL-dPEG<SUP>®</SUP><SUB>4</SUB>-(m-dPEG<SUP>®</SUP><SUB>12</SUB>)<SUB>3</SUB> 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.
