Chemical Structure
Description
2-3-4-6-Tetra-O-pivaloyl-β-D-galactopyranosyl isothiocyanate (CAS 147948-52-5) is a high-purity analytical reference standard with the molecular formula C27H43NO9S and a molecular weight of 557.70 g/mol.
The molecular framework of 2-3-4-6-Tetra-O-pivaloyl-β-D-galactopyranosyl isothiocyanate (C27H43NO9S) 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), 2-3-4-6-Tetra-O-pivaloyl-β-D-galactopyranosyl isothiocyanate 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.
