Structurally, 3(2H)-Benzoxazolepropanesulfonic acid, 2-[4-(1,3-dibutyltetrahydro-4,6-dioxo-2-thioxo-5(2H)-pyrimidinylidene)-2-butenylidene]- 3-[(2E)-2-[(E)-4-(1,3-dibutyl-4,6-dioxo-2-thioxo-hexahydropyrimidin-5-ylidene)but-2-enylidene]-1,3-benzoxazol-3-yl]propane-1-sulfonic acid 5-[(3-Sulfopropyl-2(3H)-benzoxazolylidene)-2-butenylidene]-1,3-dibutyl-2-thio-barbituric acid 62796-23-0 GEVA-NCDDG MC 540 Merocyanine 540 NSC369286 P-MC-540 (C26H38N3O6S2Na) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 575.72 g/mol, it falls into the moderately-high-molecular-weight range. 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), 3(2H)-Benzoxazolepropanesulfonic acid, 2-[4-(1,3-dibutyltetrahydro-4,6-dioxo-2-thioxo-5(2H)-pyrimidinylidene)-2-butenylidene]- 3-[(2E)-2-[(E)-4-(1,3-dibutyl-4,6-dioxo-2-thioxo-hexahydropyrimidin-5-ylidene)but-2-enylidene]-1,3-benzoxazol-3-yl]propane-1-sulfonic acid 5-[(3-Sulfopropyl-2(3H)-benzoxazolylidene)-2-butenylidene]-1,3-dibutyl-2-thio-barbituric acid 62796-23-0 GEVA-NCDDG MC 540 Merocyanine 540 NSC369286 P-MC-540 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.
