Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(Z)-({2-[(2,4-dichlorophenyl)methoxy]naphthalen-1-yl}methylidene)(methyl)oxidoazanium (CAS 321432-09-1) is a high-purity analytical reference standard with the molecular formula C19H15Cl2NO2 and a molecular weight of 360.23 g/mol.
Structurally, (Z)-({2-[(2,4-dichlorophenyl)methoxy]naphthalen-1-yl}methylidene)(methyl)oxidoazanium (C19H15Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 360.23 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.
