4-(3-Thienyl)benzenecarbaldehyde CAS 157730-74-0

Description

The occurrence of 4-(3-Thienyl)benzenecarbaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(3-Thienyl)benzenecarbaldehyde (CAS 157730-74-0), molecular formula C11H8OS and molecular weight 188.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-(3-Thienyl)benzenecarbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4-(3-Thienyl)benzenecarbaldehyde 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.
