Description
CATO manufactures 4-Epianhydrochlortetracycline Hydrochloride 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.
4-Epianhydrochlortetracycline Hydrochloride (CAS 158018-53-2) is a high-purity analytical reference standard with the molecular formula C22H21ClN2O7HCl and a molecular weight of 497.32 g/mol.
The molecular framework of 4-Epianhydrochlortetracycline Hydrochloride (C22H21ClN2O7HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
