Chemical Structure

2-Chloro-5-(difluoromethyl)benzaldehyde CAS 1785512-75-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 190.57 g/mol gives 2-Chloro-5-(difluoromethyl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-5-(difluoromethyl)benzaldehyde (CAS 1785512-75-5), molecular formula C8H5ClF2O and molecular weight 190.57 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-Chloro-5-(difluoromethyl)benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 2-Chloro-5-(difluoromethyl)benzaldehyde 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.
