5-Methyl-3-[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,2,4-oxadiazole CAS 1056456-23-5

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.

5-Methyl-3-[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,2,4-oxadiazole (CAS 1056456-23-5), molecular formula C15H19BN2O3 and molecular weight 286.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Methyl-3-[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,2,4-oxadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 5-Methyl-3-[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,2,4-oxadiazole 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.
