The occurrence of 3-Hydroxy-2-(6-methylpyridin-2-yl)-3-phenylisoindolin-1-one is closely related to a steroid 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 3-Hydroxy-2-(6-methylpyridin-2-yl)-3-phenylisoindolin-1-one (CAS 3532-40-9), a certified reference material (molecular formula C20H16N2O2, MW 316.35 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Hydroxy-2-(6-methylpyridin-2-yl)-3-phenylisoindolin-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 3-Hydroxy-2-(6-methylpyridin-2-yl)-3-phenylisoindolin-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
