Description
CATO manufactures Methyltetrazine-Ph-PEG4-azide 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.
Methyltetrazine-Ph-PEG4-azide (CAS 1802908-04-8), molecular formula C17H23N7O4 and molecular weight 389.41 g/mol, is a CATO reference standard with documented purity and traceability.
Methyltetrazine-Ph-PEG4-azide (C17H23N7O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
