6-Bromo-4-chloro-5-(difluoromethyl)picolinaldehyde CAS 1804656-47-0

Description

The occurrence of 6-Bromo-4-chloro-5-(difluoromethyl)picolinaldehyde is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Bromo-4-chloro-5-(difluoromethyl)picolinaldehyde (CAS 1804656-47-0), molecular formula C7H3BrClF2NO and molecular weight 270.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 6-Bromo-4-chloro-5-(difluoromethyl)picolinaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.46 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.
