Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 833.03 g/mol gives SR-43845 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
SR-43845 (CAS 114037-60-4), molecular formula C44H64N8O8 and molecular weight 833.03 g/mol, is a CATO reference standard with documented purity and traceability.
SR-43845 (C44H64N8O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), SR-43845 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.
