Chemical Structure

4-(Benzo[b]thiophen-3-yl)butanal CAS 1342056-69-2 chemical structure

Description

As a certified reference material (CRM), 4-(Benzo[b]thiophen-3-yl)butanal 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.

CATO supplies 4-(Benzo[b]thiophen-3-yl)butanal (CAS 1342056-69-2), a certified reference material (molecular formula C12H12OS, MW 204.29 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-(Benzo[b]thiophen-3-yl)butanal is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.29 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.
