Chemical Structure

1-Octadecyne CAS 629-89-0 chemical structure

Description

The occurrence of 1-Octadecyne is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Octadecyne (CAS 629-89-0) is a high-purity analytical reference standard with the molecular formula C18H34 and a molecular weight of 250.46 g/mol.

Structurally, 1-Octadecyne (C18H34) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 250.46 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1-Octadecyne 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.
