Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2,2'-Dihydroxy-1,1'-binaphthalene-3,3'-diboronic acid pinacol ester.
(S)-2,2'-Dihydroxy-1,1'-binaphthalene-3,3'-diboronic acid pinacol ester (CAS 1638840-73-9) is a high-purity analytical reference standard with the molecular formula C32H36B2O6 and a molecular weight of 538.25 g/mol.
(S)-2,2'-Dihydroxy-1,1'-binaphthalene-3,3'-diboronic acid pinacol ester (C32H36B2O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (S)-2,2'-Dihydroxy-1,1'-binaphthalene-3,3'-diboronic acid pinacol ester 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.
