Chemical Structure

Tenofovir disoproxil Impurity 111 CAS 1607007-18-0 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 Tenofovir disoproxil Impurity 111.

Tenofovir disoproxil Impurity 111 (CAS 1607007-18-0) is a certified pharmaceutical impurity reference standard with the molecular formula C18H26N10O7P2 and a molecular weight of 556.41 g/mol.

The molecular framework of Tenofovir disoproxil Impurity 111 (C18H26N10O7P2) is characterized by a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. 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).

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 Tenofovir disoproxil Impurity 111 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.
