Chemical Structure
Description
The occurrence of 2-(Chloromethyl)-1,3-dioxane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(Chloromethyl)-1,3-dioxane (CAS 5695-72-7), a certified reference material (molecular formula C5H9ClO2, MW 136.58 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(Chloromethyl)-1,3-dioxane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
