Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-Acetamido-3,4,6-tri-O-acetyl-2-deoxy-1-thio-beta-D-galactopyranoside.
Ethyl 2-Acetamido-3,4,6-tri-O-acetyl-2-deoxy-1-thio-beta-D-galactopyranoside (CAS 144218-98-4), molecular formula C16H25NO8S and molecular weight 391.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-Acetamido-3,4,6-tri-O-acetyl-2-deoxy-1-thio-beta-D-galactopyranoside (C16H25NO8S) is characterized by a nitrogen-containing heterocyclic scaffold, 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), Ethyl 2-Acetamido-3,4,6-tri-O-acetyl-2-deoxy-1-thio-beta-D-galactopyranoside 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.
