4-(tert-Butyl)-3-cyclopropoxybenzoic acid CAS 1243345-46-1

Description

Compared with other compounds in its class, the molecular weight of 234.29 g/mol gives 4-(tert-Butyl)-3-cyclopropoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(tert-Butyl)-3-cyclopropoxybenzoic acid (CAS 1243345-46-1), molecular formula C14H18O3 and molecular weight 234.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(tert-Butyl)-3-cyclopropoxybenzoic acid (C14H18O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 4-(tert-Butyl)-3-cyclopropoxybenzoic acid 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.
