Chemical Structure

N-(4-Ethynylphenyl)isobutyramide CAS 111448-80-7 chemical structure

Description

N-(4-Ethynylphenyl)isobutyramide (CAS 111448-80-7), molecular formula C12H13NO and molecular weight 187.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(4-Ethynylphenyl)isobutyramide (C12H13NO) 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.

CATO manufactures N-(4-Ethynylphenyl)isobutyramide 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.
