For procurement specialists and researchers in the pharmaceutical sector, a thorough understanding of chemical specifications is non-negotiable. Disodium Phosphonomycin, identified by CAS number 26016-99-9, is a prime example of a pharmaceutical intermediate where meticulous attention to specifications ensures successful application. This article delves into the critical details buyers should scrutinize when looking to purchase this vital antibiotic compound.

The most crucial specification for Disodium Phosphonomycin is its purity, typically required to be 99% or higher for pharmaceutical applications. This high purity level directly impacts the efficacy and safety of finished drug products. When you source this chemical, always request a Certificate of Analysis (CoA) that clearly states the purity percentage, often determined by HPLC. Other key physical properties to note include its appearance – a white or almost white crystalline powder – and its solubility, generally being freely soluble in water.

Beyond purity and appearance, understanding its chemical properties and adherence to standards is important. Manufacturers should specify compliance with pharmacopoeial standards like EP (European Pharmacopoeia) or USP (United States Pharmacopeia). The molecular formula (C3H5Na2O4P) and molecular weight (182.02 g/mol) are fundamental identifiers. Additionally, paying attention to details like pH range, water content, and heavy metal limits as provided in the CoA ensures the material meets the stringent requirements of pharmaceutical manufacturing.

When considering a purchase, buyers should inquire about storage conditions, as Disodium Phosphonomycin can be hygroscopic and may require storage in an inert atmosphere at specific temperatures (e.g., 2-8°C) to maintain its integrity. Reliable suppliers will offer detailed technical data sheets and readily provide safety data sheets (SDS). By thoroughly reviewing these specifications and partnering with a manufacturer that provides consistent, high-quality Disodium Phosphonomycin, you can confidently integrate this essential intermediate into your pharmaceutical development pipeline.
