Chemical Structure
Description
tert-Butyl 4-hydroxy-2,3-dihydro-1H-isoindole-2-carboxylate (CAS 871013-92-2) is a high-purity analytical reference standard with the molecular formula C13H17NO3 and a molecular weight of 235.28 g/mol.
Structurally, tert-Butyl 4-hydroxy-2,3-dihydro-1H-isoindole-2-carboxylate (C13H17NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 235.28 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
