Chemical Structure
Description
CATO supplies 6’-Desmethoxy-6’-hydroxy Noscapine (CAS 220875-41-2), a certified reference material (molecular formula C21H21NO7, MW 399.39 g/mol) for analytical method development and quality control.
6’-Desmethoxy-6’-hydroxy Noscapine (C21H21NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 6’-Desmethoxy-6’-hydroxy Noscapine 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.
