Chemical Structure
Description
The occurrence of N,N'-(Methylenebis(2-chloro-4,1-phenylene))diacetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N,N'-(Methylenebis(2-chloro-4,1-phenylene))diacetamide (CAS 91575-29-0), a certified reference material (molecular formula C17H16Cl2N2O2, MW 351.23 g/mol) for analytical method development and quality control.
Structurally, N,N'-(Methylenebis(2-chloro-4,1-phenylene))diacetamide (C17H16Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 351.23 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
