Isoniazid

Isoniazid Impurities

Isoniazid is a first-line antitubercular drug that is used in the treatment and prevention of tuberculosis. Its impurity profile includes structurally related analogs, residual solvents, and degradation products. These impurites can be formed under stress conditions such as hydrolysis, oxidation, and photolysis. Typical degradation pathways of Isoniazid may involve hydrolytic cleavage of the hydrazide group, oxidative breakdown of the pyridine ring, and rearrangement of substituents within the aromatic scaffold. These impurities may affect the potency, stability, and safety of the drug. Thus, all impurities are structurally characterized and qualified according to ICH guidelines for toxicological assessment and analytical validation.

Isoniazid EP Impurities

We provide the pharmacopeial and non-pharmacopeial Isoniazid impurity compounds that are available in compliance with European Pharmacopoeia (EP) specifications. These standards can be used for the support of analytical method development, impurity profiling, and long-term stability studies. Therefore, EP traceable materials are supplied with validated analytical data, including purity, structural confirmation, and spectral characterization.

Isoniazid Related Compounds

Structurally related compounds and synthetic analogs of Isoniazid are included for impurity identification, toxicological qualification, and regulatory submission. These related substances are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations. These Isoniazide related compounds are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Isoniazid Impurity Reference Standards

We provide Isoniazid impurity reference standards are available 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. We also synthesize the EP/USP traceable impurities that are available upon request and are routinely re-tested to ensure consistency and reliability.
