Chemical Structure
Description
The occurrence of (S)-2-Amino-3-(5-(bis(2-chloroethyl)amino)-1-(p-tolyl)-1H-benzo[d]imidazol-2-yl)propanoic acid 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 (S)-2-Amino-3-(5-(bis(2-chloroethyl)amino)-1-(p-tolyl)-1H-benzo[d]imidazol-2-yl)propanoic acid (CAS 72437-91-3), a certified reference material (molecular formula C21H24Cl2N4O2, MW 435.35 g/mol) for analytical method development and quality control.
(S)-2-Amino-3-(5-(bis(2-chloroethyl)amino)-1-(p-tolyl)-1H-benzo[d]imidazol-2-yl)propanoic acid (C21H24Cl2N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures (S)-2-Amino-3-(5-(bis(2-chloroethyl)amino)-1-(p-tolyl)-1H-benzo[d]imidazol-2-yl)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
