Chemical Structure

1-ethynyl naphthalene CAS 15727-65-8 chemical structure

Description

The occurrence of 1-ethynyl naphthalene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-ethynyl naphthalene (CAS 15727-65-8), a certified reference material (molecular formula C12H18, MW 162.27 g/mol) for analytical method development and quality control.

Owing to an aromatic ring system, 1-ethynyl naphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 162.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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

CATO manufactures 1-ethynyl naphthalene 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.
