Description
CATO manufactures Sialyl Lewis X, Methyl Glycoside under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Sialyl Lewis X, Methyl Glycoside (CAS 141612-87-5), molecular formula C32H54N2O23 and molecular weight 834.77 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Sialyl Lewis X, Methyl Glycoside is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 834.77 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).
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.
