Compared with other compounds in its class, the molecular weight of 449.92 g/mol gives Gefitinib-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Gefitinib-d3 (CAS 1173976-40-3), a certified reference material (molecular formula C22H21D3ClFN4O3, MW 449.92 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Gefitinib-d3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
