Description
As a certified reference material (CRM), Ropivacaine-d7 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.
Ropivacaine-d7 (CAS 684647-62-9) is a high-purity analytical reference standard with the molecular formula C17H19D7N2O and a molecular weight of 281.44 g/mol.
The molecular framework of Ropivacaine-d7 (C17H19D7N2O) is characterized by deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
