Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.15 g/mol gives 3-Methoxyquinoline-5-boronic acid pinacol ester, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methoxyquinoline-5-boronic acid pinacol ester, 97% (CAS 881656-35-5) is a high-purity analytical reference standard with the molecular formula C16H20BNO3 and a molecular weight of 285.15 g/mol.
The molecular framework of 3-Methoxyquinoline-5-boronic acid pinacol ester, 97% (C16H20BNO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
As a certified reference material (CRM), 3-Methoxyquinoline-5-boronic acid pinacol ester, 97% 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.
