Chemical Structure

1-(But-3-yn-1-yl)-3-phenylurea CAS 960619-87-8 chemical structure

Description

CATO manufactures 1-(But-3-yn-1-yl)-3-phenylurea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

1-(But-3-yn-1-yl)-3-phenylurea (CAS 960619-87-8) is a high-purity analytical reference standard with the molecular formula C11H12N2O and a molecular weight of 188.23 g/mol.

The molecular framework of 1-(But-3-yn-1-yl)-3-phenylurea (C11H12N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
