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 tert-Butyl 4-(2-chloropyridin-4-yloxy)naphthalen-1-ylcarbamate.
tert-Butyl 4-(2-chloropyridin-4-yloxy)naphthalen-1-ylcarbamate (CAS 1562519-39-4) is a high-purity analytical reference standard with the molecular formula C20H19ClN2O3 and a molecular weight of 370.83 g/mol.
tert-Butyl 4-(2-chloropyridin-4-yloxy)naphthalen-1-ylcarbamate (C20H19ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
CATO manufactures tert-Butyl 4-(2-chloropyridin-4-yloxy)naphthalen-1-ylcarbamate 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.
