Description
As a certified reference material (CRM), (S)-(4-Chlorophenyl)(phenyl)methanamine D(-) tartaric acid 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.
(S)-(4-Chlorophenyl)(phenyl)methanamine D(-) tartaric acid (CAS 1821739-53-0), molecular formula C13H12ClNC4H6O6 and molecular weight 367.78 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-(4-Chlorophenyl)(phenyl)methanamine D(-) tartaric acid (C13H12ClNC4H6O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
