Chemical Structure

Epn Impurity 1 CAS 32341-58-5 chemical structure

Description

The occurrence of Epn Impurity 1 is closely related to a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Epn Impurity 1 (CAS 32341-58-5), a certified reference material (molecular formula C18H13N2O6PS, MW 416.34 g/mol) for analytical method development and quality control.

The molecular framework of Epn Impurity 1 (C18H13N2O6PS) is characterized by a flavonoid core, an amide group, a sulfone group, a phosphate ester 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.

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

As a certified reference material (CRM), Epn Impurity 1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
