Chemical Structure

4,4'-Bis(3,4-dichlorophenyl)-2,2'-bithiazole CAS 328070-01-5 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 4,4'-Bis(3,4-dichlorophenyl)-2,2'-bithiazole.

4,4'-Bis(3,4-dichlorophenyl)-2,2'-bithiazole (CAS 328070-01-5) is a high-purity analytical reference standard with the molecular formula C18H8Cl4N2S2 and a molecular weight of 458.21 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4,4'-Bis(3,4-dichlorophenyl)-2,2'-bithiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 458.21 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.

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), 4,4'-Bis(3,4-dichlorophenyl)-2,2'-bithiazole 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.
