Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7'-(6-fluoropyridin-3-yl)-9'H-8'-oxa-2',4',10a'-triazaspiro[cyclopropane-1,10'-naphtho[2,1,8-cde]azulen]-2a',2a1'(4a1'),4',5',7'-pentaen-1'(2'H)-one.
7'-(6-fluoropyridin-3-yl)-9'H-8'-oxa-2',4',10a'-triazaspiro[cyclopropane-1,10'-naphtho[2,1,8-cde]azulen]-2a',2a1'(4a1'),4',5',7'-pentaen-1'(2'H)-one (CAS CATO-C3D-262508), molecular formula C19H13FN4O2 and molecular weight 348.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 7'-(6-fluoropyridin-3-yl)-9'H-8'-oxa-2',4',10a'-triazaspiro[cyclopropane-1,10'-naphtho[2,1,8-cde]azulen]-2a',2a1'(4a1'),4',5',7'-pentaen-1'(2'H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
