Chemical Structure

Nsc118075 CAS 120052-37-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 497.37 g/mol gives Nsc118075 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Nsc118075 (CAS 120052-37-1), molecular formula C22H28NO4I and molecular weight 497.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Nsc118075 (C22H28NO4I) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine 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 Nsc118075 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.
