Chemical Structure

Biotin impurity 35 CAS 1374019-64-3 chemical structure

Description

The occurrence of Biotin impurity 35 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Biotin impurity 35 (CAS 1374019-64-3) is a certified pharmaceutical impurity reference standard with the molecular formula C12H20N2O3S and a molecular weight of 272.36 g/mol.

Based on its molecular formula C12H20N2O3S, Biotin impurity 35 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Biotin impurity 35 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.
