Description
CATO manufactures Poly(1,4-butanediol)bis(4-aminobenzoate) 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.
CATO supplies Poly(1,4-butanediol)bis(4-aminobenzoate) (CAS 54667-43-5), a certified reference material (molecular formula C18H20N2O4N, MW 342.38 g/mol) for analytical method development and quality control.
Poly(1,4-butanediol)bis(4-aminobenzoate) (C18H20N2O4N) 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. 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.
