Chemical Structure

(E)-Pent-2-en-4-yn-1-ol CAS 35042-52-5 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.

(E)-Pent-2-en-4-yn-1-ol (CAS 35042-52-5), molecular formula C5H6O and molecular weight 82.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H6O, (E)-Pent-2-en-4-yn-1-ol contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 82.10 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).

As a certified reference material (CRM), (E)-Pent-2-en-4-yn-1-ol 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.
