3,4-di-tert-butylthiophene CAS 22808-03-3 chemical structure

Description

CATO supplies 3,4-di-tert-butylthiophene (CAS 22808-03-3), a certified reference material (molecular formula C12H20S, MW 196.35 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H20S, 3,4-di-tert-butylthiophene contains sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 196.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
