Diclofenac Impurity 17 CAS 43171-49-9 chemical structure

Description

Diclofenac Impurity 17 (CAS 43171-49-9) is a high-purity analytical reference standard with the molecular formula C13H10Cl2O and a molecular weight of 253.12 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Diclofenac Impurity 17 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.12 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 Diclofenac Impurity 17 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.
