Description

CATO supplies 76204-02-9 Sodium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate a-Neuraminic acid,N-acetyl-2-O-(4-methyl-2-oxo-2H-1-benzopyran-7-yl)-, monosodium salt (9CI) (CAS 76204-02-9), a certified reference material (molecular formula C21H30NNaO11H2O, MW 513.47 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 76204-02-9 Sodium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate a-Neuraminic acid,N-acetyl-2-O-(4-methyl-2-oxo-2H-1-benzopyran-7-yl)-, monosodium salt (9CI) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 513.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 76204-02-9 Sodium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate a-Neuraminic acid,N-acetyl-2-O-(4-methyl-2-oxo-2H-1-benzopyran-7-yl)-, monosodium salt (9CI) 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.
