Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.75 g/mol gives 5-Chloroquinolin-8-yl m-tolylcarbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloroquinolin-8-yl m-tolylcarbamate (CAS 21617-01-6), molecular formula C17H13ClN2O2 and molecular weight 312.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloroquinolin-8-yl m-tolylcarbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
