Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including O-(2-Azido-2-deoxy-3,4,6-tri-o-acetyl-beta-d-galactopyranosyl)-trichloroacetimidate.
CATO supplies O-(2-Azido-2-deoxy-3,4,6-tri-o-acetyl-beta-d-galactopyranosyl)-trichloroacetimidate (CAS 83025-11-0), a certified reference material (molecular formula C14H17Cl3N4O8, MW 475.67 g/mol) for analytical method development and quality control.
O-(2-Azido-2-deoxy-3,4,6-tri-o-acetyl-beta-d-galactopyranosyl)-trichloroacetimidate (C14H17Cl3N4O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), O-(2-Azido-2-deoxy-3,4,6-tri-o-acetyl-beta-d-galactopyranosyl)-trichloroacetimidate 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.
