Chemical Structure

Propiolic Acid Potassium Salt CAS 1968-46-3 chemical structure

Description

Propiolic Acid Potassium Salt (CAS 1968-46-3) is a high-purity analytical reference standard with the molecular formula C3HO2K and a molecular weight of 108.14 g/mol.

Structurally, Propiolic Acid Potassium Salt (C3HO2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 108.14 g/mol, it falls into the low-molecular-weight range. 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.

As a certified reference material (CRM), Propiolic Acid Potassium Salt 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.
