Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 383.43 g/mol gives Erlotinib Impurity 118 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Erlotinib Impurity 118 (CAS 1216420-11-9), molecular formula C21H17D4N3O4 and molecular weight 383.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Erlotinib Impurity 118 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.43 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Erlotinib Impurity 118 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.
