Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 144.21 g/mol gives 1-Ethynyl-4-isopropylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Ethynyl-4-isopropylbenzene (CAS 23152-99-0) is a high-purity analytical reference standard with the molecular formula C11H12 and a molecular weight of 144.21 g/mol.
The molecular framework of 1-Ethynyl-4-isopropylbenzene (C11H12) is characterized by an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-Ethynyl-4-isopropylbenzene 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.
