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 7-(5-((tert-Butyldiphenylsilyl)oxy)-2-chlorophenyl)-5-methylbenzo[e][1,2,4]triazin-3-amine.
7-(5-((tert-Butyldiphenylsilyl)oxy)-2-chlorophenyl)-5-methylbenzo[e][1,2,4]triazin-3-amine (CAS 1245644-51-2), molecular formula C30H29ClN4OSi and molecular weight 525.12 g/mol, is a CATO reference standard with documented purity and traceability.
7-(5-((tert-Butyldiphenylsilyl)oxy)-2-chlorophenyl)-5-methylbenzo[e][1,2,4]triazin-3-amine (C30H29ClN4OSi) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
