Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cefuroxime Impurity 75.
Cefuroxime Impurity 75 (CAS CATO-C4X-124575) is a high-purity analytical reference standard with the molecular formula C9H10N2O5 and a molecular weight of 226.19 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Cefuroxime Impurity 75 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.19 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.
CATO manufactures Cefuroxime Impurity 75 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.
