Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 570.65 g/mol gives (S)-2-Aminopentanedioic acid calcium salt(1:x) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-2-Aminopentanedioic acid calcium salt(1:x) (CAS 19238-49-4), a certified reference material (molecular formula C21H25FN6O3SC2H6O3S, MW 570.65 g/mol) for analytical method development and quality control.
(S)-2-Aminopentanedioic acid calcium salt(1:x) (C21H25FN6O3SC2H6O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (S)-2-Aminopentanedioic acid calcium salt(1:x) 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.
