Chemical Structure

Proteasome-IN-1 CAS 374080-21-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 871.92 g/mol gives Proteasome-IN-1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Proteasome-IN-1 (CAS 374080-21-4) is a high-purity analytical reference standard with the molecular formula C44H57NO17 and a molecular weight of 871.92 g/mol.

The molecular framework of Proteasome-IN-1 (C44H57NO17) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.

CATO manufactures Proteasome-IN-1 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.
