Chemical Structure

Clarithromycin Impurity 3 CAS 42008-54-8 chemical structure

Description

The occurrence of Clarithromycin Impurity 3 is closely related to sulfur-containing functionality, a hydroxyl group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Clarithromycin Impurity 3 (CAS 42008-54-8), a certified reference material (molecular formula CH4N2OS, MW 92.12 g/mol) for analytical method development and quality control.

Clarithromycin Impurity 3 (CH4N2OS) contains sulfur-containing functionality, a hydroxyl group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Clarithromycin Impurity 3 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.
