Description
1-[(11bR)-Dinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepin-4-yl]piperidine (CAS 636559-55-2), molecular formula C25H22NO2P and molecular weight 399.42 g/mol, is a CATO reference standard with documented purity and traceability.
1-[(11bR)-Dinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepin-4-yl]piperidine (C25H22NO2P) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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.
CATO manufactures 1-[(11bR)-Dinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepin-4-yl]piperidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
