Chemical Structure

(1S,3s)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxycyclobutane-1-carboxylic acid CAS 2137143-57-6 chemical structure

Description

The occurrence of (1S,3s)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxycyclobutane-1-carboxylic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (1S,3s)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxycyclobutane-1-carboxylic acid (CAS 2137143-57-6), a certified reference material (molecular formula C20H19NO5, MW 353.37 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (1S,3s)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxycyclobutane-1-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 (1S,3s)-1-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxycyclobutane-1-carboxylic acid 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.
