Chemical Structure

1-Pentyn-3-ol CAS 4187-86-4 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, 1-Pentyn-3-ol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 84.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

1-Pentyn-3-ol (CAS 4187-86-4), molecular formula C5H8O and molecular weight 84.12 g/mol, is a CATO reference standard with documented purity and traceability.

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), 1-Pentyn-3-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.
