Description

As a certified reference material (CRM), 1-[(2R,3S,4S,5R)-4-[tert-butyl(dimethyl)silyl]oxy-5-(hydroxymethyl)-3-(3-iodo-1-bicyclo[1.1.1]pentanyl)tetrahydrofuran-2-yl]pyrimidine-2,4-dione 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 1-[(2R,3S,4S,5R)-4-[tert-butyl(dimethyl)silyl]oxy-5-(hydroxymethyl)-3-(3-iodo-1-bicyclo[1.1.1]pentanyl)tetrahydrofuran-2-yl]pyrimidine-2,4-dione (CAS 2242694-24-0), a certified reference material (molecular formula C20H33IN2O5Si, MW 536.48 g/mol) for analytical method development and quality control.

Structurally, 1-[(2R,3S,4S,5R)-4-[tert-butyl(dimethyl)silyl]oxy-5-(hydroxymethyl)-3-(3-iodo-1-bicyclo[1.1.1]pentanyl)tetrahydrofuran-2-yl]pyrimidine-2,4-dione (C20H33IN2O5Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 536.48 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
