Chemical Structure
Description
Citalopram Chloromethyl Quartenary Ammonium Salt (C21H23ClFN2OCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
Citalopram Chloromethyl Quartenary Ammonium Salt (CAS CATO-C4X-110942) is a high-purity analytical reference standard with the molecular formula C21H23ClFN2OCl and a molecular weight of 409.33 g/mol.
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.
As a certified reference material (CRM), Citalopram Chloromethyl Quartenary Ammonium Salt 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.
