Chemical Structure

4-Butyl-2'-Fluorobenzophenone CAS 64357-33-1 chemical structure

Description

CATO manufactures 4-Butyl-2'-Fluorobenzophenone 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.

4-Butyl-2'-Fluorobenzophenone (CAS 64357-33-1) is a high-purity analytical reference standard with the molecular formula C17H17FO and a molecular weight of 256.31 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 4-Butyl-2'-Fluorobenzophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 256.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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