Erlotinib Impurity 124 CAS 7451-98-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Erlotinib Impurity 124.

CATO supplies Erlotinib Impurity 124 (CAS 7451-98-1), a pharmacopoeial impurity reference standard (molecular formula C9H10O3, MW 166.17 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Erlotinib Impurity 124 (C9H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 166.17 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Erlotinib Impurity 124 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.
