Chemical Structure
Description
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.
tert-Butyl N-{[3-(4-methylphenyl)-1,2,4-oxadiazol-5-yl]methyl}carbamate (CAS 1338650-26-2) is a high-purity analytical reference standard with the molecular formula C15H19N3O3 and a molecular weight of 289.33 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, tert-Butyl N-{[3-(4-methylphenyl)-1,2,4-oxadiazol-5-yl]methyl}carbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), tert-Butyl N-{[3-(4-methylphenyl)-1,2,4-oxadiazol-5-yl]methyl}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.
