Chemical Structure
Description
5-Hexynoic acid 5-Hexyn-1-oic acid 4-Ethynylbutyric acid 53293-00-8 (CAS 53293-00-8), molecular formula C6H8O2 and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Hexynoic acid 5-Hexyn-1-oic acid 4-Ethynylbutyric acid 53293-00-8 (C6H8O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 5-Hexynoic acid 5-Hexyn-1-oic acid 4-Ethynylbutyric acid 53293-00-8 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.
