Description
CATO supplies 2,3,4,6-Tetra-O-acetyl-α-D-galactopyranosyl Chloride (CAS 14227-87-3), a certified reference material (molecular formula C14H19ClO9, MW 366.75 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,3,4,6-Tetra-O-acetyl-α-D-galactopyranosyl Chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.75 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.
As a certified reference material (CRM), 2,3,4,6-Tetra-O-acetyl-α-D-galactopyranosyl Chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
