Chemical Structure

5-(tert-Butyl)-2-isopropoxyphenol CAS 1243473-35-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(tert-Butyl)-2-isopropoxyphenol.

5-(tert-Butyl)-2-isopropoxyphenol (CAS 1243473-35-9), molecular formula C13H20O2 and molecular weight 208.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(tert-Butyl)-2-isopropoxyphenol (C13H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 208.30 g/mol, it falls into the medium-molecular-weight range. 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).

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.
