2-Fluoren-9-ylidenemethylthiophene CAS 843638-98-2 chemical structure

Description

CATO manufactures 2-Fluoren-9-ylidenemethylthiophene 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.

2-Fluoren-9-ylidenemethylthiophene (CAS 843638-98-2) is a high-purity analytical reference standard with the molecular formula C18H12S and a molecular weight of 260.35 g/mol.

Owing to sulfur-containing functionality, a polycyclic aromatic system, 2-Fluoren-9-ylidenemethylthiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
