1,4-Diacetoxy-2-butyne-d4 1020719-23-6 2-Butyne-1,4-diol-(1,1,4,4)-d4, Diacetate NSC 76565-d4 (CAS 1020719-23-6) is a high-purity analytical reference standard with the molecular formula C8H6D4O4 and a molecular weight of 174.19 g/mol.
1,4-Diacetoxy-2-butyne-d4 1020719-23-6 2-Butyne-1,4-diol-(1,1,4,4)-d4, Diacetate NSC 76565-d4 (C8H6D4O4) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
As a certified reference material (CRM), 1,4-Diacetoxy-2-butyne-d4 1020719-23-6 2-Butyne-1,4-diol-(1,1,4,4)-d4, Diacetate NSC 76565-d4 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.
