Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(+)-Camptothecin D5.
CATO supplies (S)-(+)-Camptothecin D5 (CAS 1329616-37-6), a certified reference material (molecular formula C20H11D5N2O4, MW 353.38 g/mol) for analytical method development and quality control.
(S)-(+)-Camptothecin D5 (C20H11D5N2O4) contains deuterium isotope labeling, a flavonoid core, 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), (S)-(+)-Camptothecin D5 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.
