Description
The occurrence of 2-Butynedioic acid monopotassium salt 928-04-1 Acetylenedicarboxylic acid monopotassium salt acetylenedicarboxylic monopotassium acetylenedicarboxylate monopotassium butynedioate monopotassiumsaltofacetylenedicarboxylicacid potassium acetylene dicarboxylate potassium hydrogen acetylenedicarboxylate timtec-bb sbb008993 u-4783 is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Butynedioic acid monopotassium salt 928-04-1 Acetylenedicarboxylic acid monopotassium salt acetylenedicarboxylic monopotassium acetylenedicarboxylate monopotassium butynedioate monopotassiumsaltofacetylenedicarboxylicacid potassium acetylene dicarboxylate potassium hydrogen acetylenedicarboxylate timtec-bb sbb008993 u-4783 (CAS 928-04-1), molecular formula C4HO4K and molecular weight 152.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Butynedioic acid monopotassium salt 928-04-1 Acetylenedicarboxylic acid monopotassium salt acetylenedicarboxylic monopotassium acetylenedicarboxylate monopotassium butynedioate monopotassiumsaltofacetylenedicarboxylicacid potassium acetylene dicarboxylate potassium hydrogen acetylenedicarboxylate timtec-bb sbb008993 u-4783 (C4HO4K) is characterized by a carbohydrate-derived structure. 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).
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.
As a certified reference material (CRM), 2-Butynedioic acid monopotassium salt 928-04-1 Acetylenedicarboxylic acid monopotassium salt acetylenedicarboxylic monopotassium acetylenedicarboxylate monopotassium butynedioate monopotassiumsaltofacetylenedicarboxylicacid potassium acetylene dicarboxylate potassium hydrogen acetylenedicarboxylate timtec-bb sbb008993 u-4783 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.
