Chemical Structure
Description
2-Ethynylpyrimidine (CAS 37972-24-0), molecular formula C6H10N2 and molecular weight 110.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, 2-Ethynylpyrimidine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.16 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 2-Ethynylpyrimidine 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.
