Description

Uldazepam CAS NO 28546-58-9 is a benzodiazepine derivative of significant interest in pharmaceutical research and development. This compound serves as a key intermediate or active pharmaceutical ingredient (API) for investigating novel therapeutic agents targeting the central nervous system. It is primarily required by pharmaceutical manufacturers, contract research organizations (CROs), and academic institutions engaged in the synthesis of new chemical entities for preclinical and clinical studies.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of novel benzodiazepine-based drug candidates.
• Active Pharmaceutical Ingredient (API) Research: Used as a reference standard or direct component in the formulation of experimental medications for neurological and psychiatric disorders.
• Preclinical & Clinical Studies: Essential for pharmacological evaluation, including efficacy, pharmacokinetics, and toxicology profiling in research settings.
• Chemical Reference Standard: Employed in analytical laboratories for method development, validation, and quality control testing of related substances.
• Medicinal Chemistry Research: A valuable tool for structure-activity relationship (SAR) studies to optimize potency, selectivity, and safety profiles of new compounds.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for scale-up synthesis under cGMP conditions.

Quality Control

Our Uldazepam is manufactured and tested to meet high-purity standards suitable for research and pharmaceutical applications. Quality is assured through rigorous analytical controls including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each batch to ensure traceability and compliance with your research or development protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. Keep away from incompatible materials.
