Chemical Structure

Lenalidomide-acetamido-O-PEG1-C2-Cl CAS 2089207-03-2 chemical structure

Description

The occurrence of Lenalidomide-acetamido-O-PEG1-C2-Cl is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Lenalidomide-acetamido-O-PEG1-C2-Cl (CAS 2089207-03-2), molecular formula C19H22ClN3O6 and molecular weight 423.85 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Lenalidomide-acetamido-O-PEG1-C2-Cl (C19H22ClN3O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Lenalidomide-acetamido-O-PEG1-C2-Cl 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.
