4-(4-Ethylbenzoyl)isoquinoline CAS 1187169-68-1

Description

The occurrence of 4-(4-Ethylbenzoyl)isoquinoline is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(4-Ethylbenzoyl)isoquinoline (CAS 1187169-68-1), molecular formula C18H15NO and molecular weight 261.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-Ethylbenzoyl)isoquinoline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.32 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.

CATO manufactures 4-(4-Ethylbenzoyl)isoquinoline 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.
