Furosemide Impurity 27 CAS 2760-11-4

Description

The occurrence of Furosemide Impurity 27 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Furosemide Impurity 27 (CAS 2760-11-4), a pharmacopoeial impurity reference standard (molecular formula C7H6Cl2N2O3S, MW 269.11 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Furosemide Impurity 27 (C7H6Cl2N2O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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 269.11 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Furosemide Impurity 27 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
