Chemical Structure
Description
The occurrence of Sucralose EP Impurity A 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 Sucralose EP Impurity A (CAS 105066-21-5), a certified reference material (molecular formula C14H21Cl3O9, MW 439.67 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Sucralose EP Impurity A is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.67 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
