Chemical Structure
Description
As a certified reference material (CRM), 4,4',4'',4'''-(Thiophene-2,3,4,5-tetrayl)tetrapyridine 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.
4,4',4'',4'''-(Thiophene-2,3,4,5-tetrayl)tetrapyridine (CAS 64048-12-0), molecular formula C24H16N4S and molecular weight 392.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4',4'',4'''-(Thiophene-2,3,4,5-tetrayl)tetrapyridine (C24H16N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
