Chemical Structure
Description
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.
N-(4'-bromo-[1,1'-biphenyl]-4-yl)-3-chlorobenzamide (CAS 331762-07-3), molecular formula C19H13BrClNO and molecular weight 386.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(4'-bromo-[1,1'-biphenyl]-4-yl)-3-chlorobenzamide (C19H13BrClNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 386.67 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
