Description

CATO manufactures Methyl 4-((1-cyclobutyl-4-oxo-4,5,6,7,8,9-hexahydro-3H-pyrazolo[3,4-c]quinolin-3-yl)methyl)picolinate 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 Methyl 4-((1-cyclobutyl-4-oxo-4,5,6,7,8,9-hexahydro-3H-pyrazolo[3,4-c]quinolin-3-yl)methyl)picolinate (CAS 1464091-45-9), a certified reference material (molecular formula C22H24N4O3, MW 392.45 g/mol) for analytical method development and quality control.

Methyl 4-((1-cyclobutyl-4-oxo-4,5,6,7,8,9-hexahydro-3H-pyrazolo[3,4-c]quinolin-3-yl)methyl)picolinate (C22H24N4O3) contains a steroid 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.
