Description
CATO supplies tert-butyl (3R)-3-[(5-bromo-6-chloro-2-cyano-3-pyridyl)oxymethyl]piperidine-1-carboxylate (CAS 1858215-57-2), a certified reference material (molecular formula C17H21BrClN3O3, MW 430.72 g/mol) for analytical method development and quality control.
Structurally, tert-butyl (3R)-3-[(5-bromo-6-chloro-2-cyano-3-pyridyl)oxymethyl]piperidine-1-carboxylate (C17H21BrClN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 430.72 g/mol, it falls into the moderately-high-molecular-weight range. 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), tert-butyl (3R)-3-[(5-bromo-6-chloro-2-cyano-3-pyridyl)oxymethyl]piperidine-1-carboxylate 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.
