Chemical Structure

N,N'-([4,4'-Bithiazole]-2,2'-diyl)bis(2-iodobenzamide) CAS 393838-80-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,N'-([4,4'-Bithiazole]-2,2'-diyl)bis(2-iodobenzamide).

CATO supplies N,N'-([4,4'-Bithiazole]-2,2'-diyl)bis(2-iodobenzamide) (CAS 393838-80-7), a certified reference material (molecular formula C20H12I2N4O2S2, MW 658.27 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, N,N'-([4,4'-Bithiazole]-2,2'-diyl)bis(2-iodobenzamide) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 658.27 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.

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.

As a certified reference material (CRM), N,N'-([4,4'-Bithiazole]-2,2'-diyl)bis(2-iodobenzamide) 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.
