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 Ethyl 2-[(3-Bromo-4-pyridyl)thio]-2-methylpropanoate.
Ethyl 2-[(3-Bromo-4-pyridyl)thio]-2-methylpropanoate (CAS 1352794-86-5), molecular formula C11H14BrNO2S and molecular weight 304.20 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-[(3-Bromo-4-pyridyl)thio]-2-methylpropanoate (C11H14BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
