Chemical Structure

2,5-Anhydro D-Mannose Oxime, Technical grade CAS 127676-61-3 chemical structure

Description

2,5-Anhydro D-Mannose Oxime, Technical grade (CAS 127676-61-3), molecular formula C6H11NO5 and molecular weight 177.16 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Anhydro D-Mannose Oxime, Technical grade (C6H11NO5) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
