Chemical Structure

3,4-Dichloro-3-fluoro-5-methylbenzophenone CAS 951886-99-0 chemical structure

Description

The occurrence of 3,4-Dichloro-3-fluoro-5-methylbenzophenone is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4-Dichloro-3-fluoro-5-methylbenzophenone (CAS 951886-99-0), molecular formula C14H9Cl2FO and molecular weight 283.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H9Cl2FO, 3,4-Dichloro-3-fluoro-5-methylbenzophenone contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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

As a certified reference material (CRM), 3,4-Dichloro-3-fluoro-5-methylbenzophenone 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.
