Chemical Structure

3-Ethynyl-2-fluorobenzaldehyde CAS 1851952-10-7 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.

3-Ethynyl-2-fluorobenzaldehyde (CAS 1851952-10-7) is a high-purity analytical reference standard with the molecular formula C9H5FO and a molecular weight of 148.13 g/mol.

3-Ethynyl-2-fluorobenzaldehyde (C9H5FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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), 3-Ethynyl-2-fluorobenzaldehyde 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.
