Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [8-ethynyl-7-fluoro-3-(methoxymethoxy)-1-naphthyl]boronic acid.
[8-ethynyl-7-fluoro-3-(methoxymethoxy)-1-naphthyl]boronic acid (CAS 2839189-85-2) is a high-purity analytical reference standard with the molecular formula C14H12BFO4 and a molecular weight of 274.05 g/mol.
Based on its molecular formula C14H12BFO4, [8-ethynyl-7-fluoro-3-(methoxymethoxy)-1-naphthyl]boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 [8-ethynyl-7-fluoro-3-(methoxymethoxy)-1-naphthyl]boronic 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.
