Chemical Structure
Description
4-Methylumbelliferyl 6-Sulfo-2-acetamido-2-deoxy-a-D-glucopyranoside (CAS 154639-35-7), molecular formula C18H20NO11SK and molecular weight 497.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methylumbelliferyl 6-Sulfo-2-acetamido-2-deoxy-a-D-glucopyranoside (C18H20NO11SK) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Methylumbelliferyl 6-Sulfo-2-acetamido-2-deoxy-a-D-glucopyranoside 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.
