2-(Difluoromethyl)-3-methoxythiophene CAS 2149591-23-9 chemical structure

Description

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.

2-(Difluoromethyl)-3-methoxythiophene (CAS 2149591-23-9) is a high-purity analytical reference standard with the molecular formula C6H6F2OS and a molecular weight of 164.17 g/mol.

2-(Difluoromethyl)-3-methoxythiophene (C6H6F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 2-(Difluoromethyl)-3-methoxythiophene 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.
