Chemical Structure
Description
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.
Ethyl 2',4'-dichloro-5'-oxo-6',8'-dihydro-5'H-spiro[cyclohexane-1,7'-quinoline]-3'-carboxylate (CAS 1384265-55-7) is a high-purity analytical reference standard with the molecular formula C17H19Cl2NO3 and a molecular weight of 356.24 g/mol.
Structurally, Ethyl 2',4'-dichloro-5'-oxo-6',8'-dihydro-5'H-spiro[cyclohexane-1,7'-quinoline]-3'-carboxylate (C17H19Cl2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 356.24 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).
CATO manufactures Ethyl 2',4'-dichloro-5'-oxo-6',8'-dihydro-5'H-spiro[cyclohexane-1,7'-quinoline]-3'-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
