Trimethoprim

Trimethoprim Impurities

Trimethoprim impurities include synthetic intermediates, process-related compounds, degradation products, and potential residual solvents that may arise during synthesis, formulation, or storage. As a dihydrofolate reductase inhibitor used primarily in the treatment of urinary tract infections and other bacterial conditions, impurity profiling is essential to ensure product safety, therapeutic efficacy, and regulatory compliance. All impurity compounds are structurally characterized and qualified under ICH guidelines for toxicological evaluation and analytical validation.

Trimethoprim EP Impurities

Pharmacopeial and non-pharmacopeial Trimethoprim impurity compounds are available in compliance with European Pharmacopoeia (EP) specifications. These standards support analytical method development, impurity profiling, and stability testing. EP traceable materials are supplied with validated analytical data including purity, structural confirmation, and spectral characterization.

Trimethoprim Related Compounds

Structurally related compounds and synthetic analogs associated with Trimethoprim are included for use in impurity identification, toxicological qualification, and regulatory submission. These materials are thoroughly characterized and conform to international standards. Related compounds are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations.

Trimethoprim Impurity Reference Standards

Trimethoprim impurity reference standards are provided with validated analytical data including purity, NMR, MS, and full Certificates of Analysis. These standards are used in pharmaceutical research, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
