Chemical Structure
Description
4-Chloro-2-(phenylethynyl)aniline (CAS 928782-97-2) is a high-purity analytical reference standard with the molecular formula C14H10ClN and a molecular weight of 227.69 g/mol.
The molecular framework of 4-Chloro-2-(phenylethynyl)aniline (C14H10ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Chloro-2-(phenylethynyl)aniline 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.
