5-[7-(2-Thienyl)-2,1,3-benzothiadiazol-4-yl]-2-thiophenecarboxaldehyde CAS 1042440-26-5

Description

5-[7-(2-Thienyl)-2,1,3-benzothiadiazol-4-yl]-2-thiophenecarboxaldehyde (CAS 1042440-26-5) is a high-purity analytical reference standard with the molecular formula C15H8N2OS3 and a molecular weight of 328.43 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-[7-(2-Thienyl)-2,1,3-benzothiadiazol-4-yl]-2-thiophenecarboxaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-[7-(2-Thienyl)-2,1,3-benzothiadiazol-4-yl]-2-thiophenecarboxaldehyde 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.
