Chemical Structure

4-(Prop-2-yn-1-yl)benzaldehyde CAS 51205-88-0 chemical structure

Description

4-(Prop-2-yn-1-yl)benzaldehyde (CAS 51205-88-0) is a high-purity analytical reference standard with the molecular formula C10H8O and a molecular weight of 144.17 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 4-(Prop-2-yn-1-yl)benzaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
