4-tert-Butyl-2-ethylbenzophenone CAS 951884-94-9 chemical structure

Description

CATO manufactures 4-tert-Butyl-2-ethylbenzophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 4-tert-Butyl-2-ethylbenzophenone (CAS 951884-94-9), a certified reference material (molecular formula C19H22O, MW 266.38 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 4-tert-Butyl-2-ethylbenzophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
