Chemical Structure
Description
As a certified reference material (CRM), Ethyl hept-3-ynoate 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.
Ethyl hept-3-ynoate (CAS 89216-44-4), molecular formula C9H14O2 and molecular weight 154.21 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl hept-3-ynoate (C9H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
