For pharmaceutical buyers, a thorough understanding of API specifications is fundamental to successful procurement and formulation. Methotrexate (CAS 59-05-2), a critical compound in both chemotherapy and immunosuppressive therapies, demands specific attention to its quality parameters. As a dedicated manufacturer, we aim to provide clarity on these specifications, ensuring our clients can make informed purchasing decisions.

The appearance of Methotrexate is typically described as an orange-yellow crystalline powder. This physical characteristic is an initial indicator of product quality and consistency. Deviations from this standard can suggest issues with the manufacturing or storage process, underscoring the importance of sourcing from reputable suppliers who maintain strict quality control over the physical attributes of the API.

Purity is arguably the most critical specification for any API, and Methotrexate is no exception. Our standard offering guarantees a minimum purity of 99.00-102.00%. This high level of purity is essential to ensure the drug's therapeutic efficacy and to minimize the risk of unintended side effects arising from impurities. Pharmaceutical formulations demand APIs that are not only potent but also extremely pure to meet regulatory standards and patient safety requirements.

Storage conditions are also vital for maintaining the integrity of Methotrexate. The material is noted as being stable, but sensitive to light and hygroscopic. Therefore, it requires storage at -15°C or below, and protection from light. As a manufacturer, we adhere to these conditions rigorously throughout our warehousing and shipping processes. We advise our clients to maintain similar conditions upon receipt to preserve the API's quality and shelf-life.

Other specifications, such as melting point (185-204°C), molecular weight (454.44), related substances (≤1.0%), loss on drying (≤0.5%), and heavy metals (≤20ppm), provide further assurance of the API's quality and suitability for pharmaceutical use. These parameters are systematically monitored during our manufacturing process.

Navigating these specifications can seem complex, but for pharmaceutical buyers, it's about ensuring reliability and compliance. We pride ourselves on providing transparent and accurate documentation for our Methotrexate, empowering our clients with the information they need. If you are looking to purchase Methotrexate and require detailed technical specifications or a price inquiry, please do not hesitate to contact our expert team.
