Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-(2-(2-((3-(furan-3-yl)phenyl)amino)-2-oxoethoxy)acetamido)benzoic acid.
5-Chloro-2-(2-(2-((3-(furan-3-yl)phenyl)amino)-2-oxoethoxy)acetamido)benzoic acid (CAS 1190221-43-2), molecular formula C21H17ClN2O6 and molecular weight 428.82 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Chloro-2-(2-(2-((3-(furan-3-yl)phenyl)amino)-2-oxoethoxy)acetamido)benzoic acid (C21H17ClN2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 428.82 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), 5-Chloro-2-(2-(2-((3-(furan-3-yl)phenyl)amino)-2-oxoethoxy)acetamido)benzoic 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.
