Chemical Structure

2-tert-butyl-1,3-benzoxazole CAS 54696-03-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 175.23 g/mol gives 2-tert-butyl-1,3-benzoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-tert-butyl-1,3-benzoxazole (CAS 54696-03-6), a certified reference material (molecular formula C11H13NO, MW 175.23 g/mol) for analytical method development and quality control.

Structurally, 2-tert-butyl-1,3-benzoxazole (C11H13NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 175.23 g/mol, it falls into the medium-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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
