Description
tert-butyl N-[(3R,6S)-6-{[(tert-butyldiphenylsilyl)oxy]methyl}-3,6-dihydro-2H-pyran-3-yl]carbamate (CAS 1638744-61-2) is a high-purity analytical reference standard with the molecular formula C27H49NO4Si and a molecular weight of 479.77 g/mol.
The molecular framework of tert-butyl N-[(3R,6S)-6-{[(tert-butyldiphenylsilyl)oxy]methyl}-3,6-dihydro-2H-pyran-3-yl]carbamate (C27H49NO4Si) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), tert-butyl N-[(3R,6S)-6-{[(tert-butyldiphenylsilyl)oxy]methyl}-3,6-dihydro-2H-pyran-3-yl]carbamate 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.
