Chemical Structure
Description
As a certified reference material (CRM), 2-(N-Boc-N-butylamino)-5-bromopyridine 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.
2-(N-Boc-N-butylamino)-5-bromopyridine (CAS 1291487-21-2), molecular formula C14H21BrN2O2 and molecular weight 329.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(N-Boc-N-butylamino)-5-bromopyridine (C14H21BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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 329.23 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
