Chemical Structure
Description
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.
CATO supplies Methyl 3-(N-(4-((tert-butyldimethylsilyl)oxy)cyclohexyl)-4-methylcyclohexanecarboxamido)-5-iodothiophene-2-carboxylate (CAS 1263101-57-0), a certified reference material (molecular formula C26H42INO4SSi, MW 619.67 g/mol) for analytical method development and quality control.
Methyl 3-(N-(4-((tert-butyldimethylsilyl)oxy)cyclohexyl)-4-methylcyclohexanecarboxamido)-5-iodothiophene-2-carboxylate (C26H42INO4SSi) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
