Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.22 g/mol gives tert-Butyl (2-(3-bromothiophen-2-yl)ethyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl (2-(3-bromothiophen-2-yl)ethyl)carbamate (CAS 2143528-87-2), a certified reference material (molecular formula C11H16BrNO2S, MW 306.22 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl (2-(3-bromothiophen-2-yl)ethyl)carbamate (C11H16BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 306.22 g/mol, it falls into the moderately-high-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.
