Chemical Structure
Description
Structurally, 3-((Z)-2-((3-(2-Carboxyethyl)-5-(((R)-3-ethyl-4-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-1H-pyrrol-2-yl)methylene)-5-(((R)-4-ethyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-2H-pyrrol-3-yl)propanoic acid (C33H42N4O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 590.71 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).
3-((Z)-2-((3-(2-Carboxyethyl)-5-(((R)-3-ethyl-4-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-1H-pyrrol-2-yl)methylene)-5-(((R)-4-ethyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-2H-pyrrol-3-yl)propanoic acid (CAS 6921-61-5), molecular formula C33H42N4O6 and molecular weight 590.71 g/mol, is a CATO reference standard with documented purity and traceability.
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-((Z)-2-((3-(2-Carboxyethyl)-5-(((R)-3-ethyl-4-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-1H-pyrrol-2-yl)methylene)-5-(((R)-4-ethyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-yl)methyl)-4-methyl-2H-pyrrol-3-yl)propanoic acid 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.
