1-(4-Ethoxyphenyl)-3-propylthiourea CAS 431922-74-6

Description

Compared with other compounds in its class, the molecular weight of 238.35 g/mol gives 1-(4-Ethoxyphenyl)-3-propylthiourea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(4-Ethoxyphenyl)-3-propylthiourea (CAS 431922-74-6) is a high-purity analytical reference standard with the molecular formula C12H18N2OS and a molecular weight of 238.35 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-(4-Ethoxyphenyl)-3-propylthiourea is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 238.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 1-(4-Ethoxyphenyl)-3-propylthiourea 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.
