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 (1-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,3-dihydro-1H-inden-2-yl)carbamate.
Ethyl (1-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,3-dihydro-1H-inden-2-yl)carbamate (CAS 306978-20-1) is a high-purity analytical reference standard with the molecular formula C18H16ClF3N2O2S and a molecular weight of 416.85 g/mol.
Ethyl (1-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,3-dihydro-1H-inden-2-yl)carbamate (C18H16ClF3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ethyl (1-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,3-dihydro-1H-inden-2-yl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
