In the demanding field of pharmaceutical development and manufacturing, precise specifications for raw materials and intermediates are non-negotiable. Ceftriaxone EP Impurity E (CAS 58909-56-1) is a prime example of a chemical that requires thorough specification understanding for effective procurement. As a leading manufacturer and supplier, we emphasize the importance of these details for our B2B clients.

The Foundation: CAS Number and Chemical Identity

Every batch of Ceftriaxone EP Impurity E we provide is unequivocally identified by its CAS number: 58909-56-1. This unique identifier is crucial for accurate tracking, regulatory compliance, and ensuring that the correct compound is being used in synthesis. Beyond the CAS number, its systematic chemical name, often cited as (6R,7R)-7-Amino-8-oxo-3-[[(1,2,5,6-tetrahydro-2-methyl-5,6-dioxo-1,2,4-triazin-3-yl)thio]methyl]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, provides further confirmation of its structure.

Purity: The Non-Negotiable Specification

For pharmaceutical intermediates, purity is paramount. Ceftriaxone EP Impurity E is typically supplied with a purity exceeding 95%. This high purity is critical to prevent the introduction of unwanted contaminants into the final API. As a dedicated manufacturer, our quality control processes are designed to consistently achieve and verify this purity level. We provide detailed analytical data, including HPLC chromatograms and NMR spectra, to substantiate our claims, empowering you to make informed purchasing decisions when you buy.

Molecular Details: Formula and Weight

Understanding the molecular formula and weight is also essential for stoichiometric calculations and process optimization. Ceftriaxone EP Impurity E has the molecular formula C12H13N5O5S2 and a molecular weight of approximately 371.39212. These figures are fundamental for R&D scientists and formulation chemists when incorporating this intermediate into their processes.

Appearance and Physical Properties

While often supplied as a solid (powder), understanding its physical characteristics can aid in handling and storage. Any supplier should be able to provide information on its appearance, such as color (typically off-white) and physical state. This information, coupled with its molecular properties, helps to ensure correct storage and handling procedures.

Why Partner with a Dedicated Manufacturer?

When you are ready to purchase Ceftriaxone EP Impurity E, choosing a dedicated manufacturer, especially one based in China, offers distinct advantages. These include:

  • Guaranteed Specifications: Direct manufacturers have control over their production and quality assurance.
  • Competitive Pricing: Eliminating intermediaries often leads to better value.
  • Technical Support: Access to expert knowledge regarding the product.
  • Reliable Supply: Ensuring your production lines are never stalled.

By prioritizing these key specifications and partnering with a trustworthy supplier, pharmaceutical companies can confidently integrate Ceftriaxone EP Impurity E into their critical manufacturing processes, ensuring the quality and safety of their end products.
