Chemical Structure
Description
The occurrence of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (7-chloro-2-oxoindolin-5-yl)boronate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (7-chloro-2-oxoindolin-5-yl)boronate (CAS 1809203-85-7) is a high-purity analytical reference standard with the molecular formula C14H19BClNO4 and a molecular weight of 311.57 g/mol.
The molecular framework of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (7-chloro-2-oxoindolin-5-yl)boronate (C14H19BClNO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
