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 4-(Benzyloxycarbonyl)benzeneboronic Acid.
4-(Benzyloxycarbonyl)benzeneboronic Acid (CAS 184000-11-1) is a high-purity analytical reference standard with the molecular formula C14H13BO4 and a molecular weight of 256.06 g/mol.
Based on its molecular formula C14H13BO4, 4-(Benzyloxycarbonyl)benzeneboronic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
