The molecular framework of 7HZA2PL15F 762-42-5 Acetylenedicarboxylic acid dimethyl ester Acetylenedicarboxylic acid, dimethyl ester (8CI) 2-Butynedioic acid, dimethyl ester Dimethyl butynedioate 2-Butynedioic acid, 1,4-dimethyl ester 4-02-00-02291 (Beilstein Handbook Reference) Acetylenedicarboxylic acid, dimethyl ester Bis(methoxycarbonyl)acetylene 1,2-Bis(methoxycarbonyl)acetylene 1,2-Bis(methoxycarbonyl)ethyne BRN 0607063 Di(carbomethoxy)acetylene Dimethyl acetylenedicarboxylic acid Dimethyl 2-butynedioate Dimethyl ethynedicarboxylate EINECS 212-098-4 Methyl acetylenedicarboxylate NSC 14912 UNII-7HZA2PL15F (C6H6O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
