Chemical Structure

2-Chloro-6-ethynylpyridine CAS 914950-09-7 chemical structure

Description

2-Chloro-6-ethynylpyridine (C7H4ClN) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

2-Chloro-6-ethynylpyridine (CAS 914950-09-7) is a high-purity analytical reference standard with the molecular formula C7H4ClN and a molecular weight of 137.57 g/mol.

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), 2-Chloro-6-ethynylpyridine 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.
