Chemical Structure

Nifuratel Impurity 16 CAS 19987-13-4 chemical structure

Description

Nifuratel Impurity 16 (C4H9ClS) contains sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Nifuratel Impurity 16 (CAS 19987-13-4) is a high-purity analytical reference standard with the molecular formula C4H9ClS and a molecular weight of 124.63 g/mol.

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 Nifuratel Impurity 16 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.
