Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-((7-bromo-3,3-dibutyl-1,1-dioxido-5-phenyl-2,3,4,5-tetrahydrobenzo[f][1,2,5]thiadiazepin-8-yl)oxy)acetate.
Ethyl 2-((7-bromo-3,3-dibutyl-1,1-dioxido-5-phenyl-2,3,4,5-tetrahydrobenzo[f][1,2,5]thiadiazepin-8-yl)oxy)acetate (CAS 501692-59-7), molecular formula C26H35BrN2O5S and molecular weight 567.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 2-((7-bromo-3,3-dibutyl-1,1-dioxido-5-phenyl-2,3,4,5-tetrahydrobenzo[f][1,2,5]thiadiazepin-8-yl)oxy)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 567.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
