Chemical Structure
Description
The occurrence of tert-Butyl N-[1-({[(3-chlorophenyl)carbamoyl]amino}methyl)cycloheptyl]carbamate 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.
tert-Butyl N-[1-({[(3-chlorophenyl)carbamoyl]amino}methyl)cycloheptyl]carbamate (CAS 1253528-14-1), molecular formula C20H30ClN3O3 and molecular weight 395.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl N-[1-({[(3-chlorophenyl)carbamoyl]amino}methyl)cycloheptyl]carbamate (C20H30ClN3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
