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 tert-Butyl (2-hydroxy-1-(o-tolyl)ethyl)carbamate.
tert-Butyl (2-hydroxy-1-(o-tolyl)ethyl)carbamate (CAS 1824436-01-2) is a high-purity analytical reference standard with the molecular formula C14H21NO3 and a molecular weight of 251.32 g/mol.
Structurally, tert-Butyl (2-hydroxy-1-(o-tolyl)ethyl)carbamate (C14H21NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 251.32 g/mol, it falls into the medium-molecular-weight range. 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.
