Chemical Structure

4-n-Pentoxythiophenol CAS 61519-09-3 chemical structure

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-n-Pentoxythiophenol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

4-n-Pentoxythiophenol (CAS 61519-09-3), molecular formula C11H16OS and molecular weight 196.31 g/mol, is a CATO reference standard with documented purity and traceability.

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-n-Pentoxythiophenol 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.
