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.
2-Chloro-3-[4-(4-chlorophenyl)cyclohexyl-d5]-1,4-naphthalenedione (CAS 1189507-64-9) is a high-purity analytical reference standard with the molecular formula C22H13D5Cl2O2 and a molecular weight of 390.31 g/mol.
Structurally, 2-Chloro-3-[4-(4-chlorophenyl)cyclohexyl-d5]-1,4-naphthalenedione (C22H13D5Cl2O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 390.31 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
