(2E)-3-(4-tert-Butylphenyl)-1-(4-methylphenyl)prop-2-en-1-one CAS 1252617-33-6 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 (2E)-3-(4-tert-Butylphenyl)-1-(4-methylphenyl)prop-2-en-1-one.

(2E)-3-(4-tert-Butylphenyl)-1-(4-methylphenyl)prop-2-en-1-one (CAS 1252617-33-6), molecular formula C20H22O and molecular weight 278.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2E)-3-(4-tert-Butylphenyl)-1-(4-methylphenyl)prop-2-en-1-one (C20H22O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 278.39 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.

As a certified reference material (CRM), (2E)-3-(4-tert-Butylphenyl)-1-(4-methylphenyl)prop-2-en-1-one 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.
