Chemical Structure
Description
D-galactose Sodium (CAS 18315-92-9), molecular formula C6H12O7Na and molecular weight 219.15 g/mol, is a CATO reference standard with documented purity and traceability.
D-galactose Sodium (C6H12O7Na) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), D-galactose Sodium 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.
