Description
As a certified reference material (CRM), 3’-Hydroxy Stanozolol-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.
CATO supplies 3’-Hydroxy Stanozolol-d5 (CAS 853904-68-4), a certified reference material (molecular formula C21H27D5N2O2, MW 349.52 g/mol) for analytical method development and quality control.
3’-Hydroxy Stanozolol-d5 (C21H27D5N2O2) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
