3-tert-Butylthiophene CAS 1689-79-8 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.

3-tert-Butylthiophene (CAS 1689-79-8), molecular formula C8H12S and molecular weight 140.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H12S, 3-tert-Butylthiophene contains sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 140.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3-tert-Butylthiophene 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.
