Description

As a certified reference material (CRM), 3383-21-9 3,5-Di-tert-butyl-1,2-benzoquinone o-Benzoquinone, 3,5-di-tert-butyl- (8CI) 3,5-Cyclohexadiene-1,2-dione, 3,5-bis(1,1-dimethylethyl)- (9CI) 3,5-Di-tert-butyl-o-benzoquinone EINECS 222-189-0 NSC 149061 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.

3383-21-9 3,5-Di-tert-butyl-1,2-benzoquinone o-Benzoquinone, 3,5-di-tert-butyl- (8CI) 3,5-Cyclohexadiene-1,2-dione, 3,5-bis(1,1-dimethylethyl)- (9CI) 3,5-Di-tert-butyl-o-benzoquinone EINECS 222-189-0 NSC 149061 (CAS 3383-21-9), molecular formula C14H20O2 and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H20O2, 3383-21-9 3,5-Di-tert-butyl-1,2-benzoquinone o-Benzoquinone, 3,5-di-tert-butyl- (8CI) 3,5-Cyclohexadiene-1,2-dione, 3,5-bis(1,1-dimethylethyl)- (9CI) 3,5-Di-tert-butyl-o-benzoquinone EINECS 222-189-0 NSC 149061 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.31 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).

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