Chemical Structure

Thionicotinamide CAS 4621-66-3 chemical structure

Description

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 supplies Thionicotinamide (CAS 4621-66-3), a certified reference material (molecular formula C6H6N2S, MW 138.19 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, Thionicotinamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures Thionicotinamide 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.
