Chemical Structure

4-Methoxybut-2-ynal CAS 32462-08-1 chemical structure

Description

CATO supplies 4-Methoxybut-2-ynal (CAS 32462-08-1), a certified reference material (molecular formula C5H6O2, MW 98.10 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H6O2, 4-Methoxybut-2-ynal contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 98.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-Methoxybut-2-ynal 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.
