Chemical Structure
Description
The occurrence of Aripiprazole 3,4-Dichloro Analog 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.
Aripiprazole 3,4-Dichloro Analog (CAS 203395-75-9) is a high-purity analytical reference standard with the molecular formula C23H27Cl2N3O2 and a molecular weight of 448.39 g/mol.
Aripiprazole 3,4-Dichloro Analog (C23H27Cl2N3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Aripiprazole 3,4-Dichloro Analog meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
