Chemical Structure
Description
The molecular framework of 4-(tert-Butoxy)-2-cyclopropoxy-1-methoxybenzene (C14H20O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
4-(tert-Butoxy)-2-cyclopropoxy-1-methoxybenzene (CAS 1243450-63-6), molecular formula C14H20O3 and molecular weight 236.31 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-(tert-Butoxy)-2-cyclopropoxy-1-methoxybenzene 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.
