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 N-tert-Butoxycarbonyl 1-(3-Methylbenzyl)piperazine.
N-tert-Butoxycarbonyl 1-(3-Methylbenzyl)piperazine (CAS 203047-32-9), molecular formula C17H26N2O2 and molecular weight 290.40 g/mol, is a CATO reference standard with documented purity and traceability.
N-tert-Butoxycarbonyl 1-(3-Methylbenzyl)piperazine (C17H26N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
