2-tert-Butyl-4,5-dimethylphenol CAS 1445-23-4

Description

The occurrence of 2-tert-Butyl-4,5-dimethylphenol is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-tert-Butyl-4,5-dimethylphenol (CAS 1445-23-4) is a high-purity analytical reference standard with the molecular formula C12H18O and a molecular weight of 178.27 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-tert-Butyl-4,5-dimethylphenol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 178.27 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).

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.
