The occurrence of Cycloguanil Embonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Cycloguanil Embonate (CAS 609-78-9) is a high-purity analytical reference standard with the molecular formula C23H16O6C11H14ClN5 and a molecular weight of 640.09 g/mol.
Structurally, Cycloguanil Embonate (C23H16O6C11H14ClN5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 640.09 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Cycloguanil Embonate 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.
