1-Pentyne CAS 627-19-0 chemical structure

Description

1-Pentyne (CAS 627-19-0) is a high-purity analytical reference standard with the molecular formula C5H8 and a molecular weight of 68.12 g/mol.

The molecular framework of 1-Pentyne (C5H8) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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-Pentyne 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.
