Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,3,6-Trimethoxy Benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.20 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).
CATO supplies 2,3,6-Trimethoxy Benzaldehyde (CAS 5556-86-5), a certified reference material (molecular formula C10H12O4, MW 196.20 g/mol) for analytical method development and quality control.
