Chemical Structure
Description
The occurrence of 4-((5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)ethynyl)benzoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-((5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)ethynyl)benzoic acid (CAS 104561-41-3) is a high-purity analytical reference standard with the molecular formula C23H24O2 and a molecular weight of 332.44 g/mol.
The molecular framework of 4-((5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)ethynyl)benzoic acid (C23H24O2) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-((5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)ethynyl)benzoic acid 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.
