Chemical Structure

Penta-1,4-diyn-3-ol CAS 56598-53-9 chemical structure

Description

CATO manufactures Penta-1,4-diyn-3-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Penta-1,4-diyn-3-ol (CAS 56598-53-9), a certified reference material (molecular formula C5H4O, MW 80.08 g/mol) for analytical method development and quality control.

Structurally, Penta-1,4-diyn-3-ol (C5H4O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 80.08 g/mol, it falls into the low-molecular-weight range. 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.
