For procurement professionals and researchers in the pharmaceutical industry, understanding the factors that influence the pricing of Active Pharmaceutical Ingredient (API) intermediates is key to making informed purchasing decisions. The cost of a complex intermediate like N-(4,5-dimethylisoxazol-3-yl)-2'-(ethoxymethyl)-4'-(hydroxymethyl)-N-(methoxymethyl)-[1,1'-biphenyl]-2-sulfonamide, identified by CAS number 1098924-76-5, is a result of several intertwined elements.

The primary driver for the price of any chemical intermediate is its synthesis complexity. The molecular structure of CAS 1098924-76-5 (C23H28N2O6S, MW 460.54) suggests a multi-step synthetic process, likely involving specialized reagents, controlled reaction conditions, and potentially advanced purification techniques. The more intricate the synthesis, the higher the labor, energy, and raw material costs for the manufacturer, which ultimately reflects in the final product price.

Purity levels also play a significant role. Intermediates destined for pharmaceutical use often require exceptionally high purity (e.g., NLT 98%). Achieving such purity typically necessitates more rigorous purification steps, such as chromatography or multiple recrystallizations, adding to the production cost. When you buy an intermediate, the quoted price often reflects this guaranteed purity standard, a critical quality assurance for API manufacturing.

Scale of production is another major factor. For larger batch sizes, the cost per unit tends to decrease due to economies of scale. A manufacturer can amortize fixed costs over a larger volume, and certain processes become more efficient at scale. Therefore, the price for kilogram quantities of CAS 1098924-76-5 will generally be lower than for gram quantities, unless custom synthesis for smaller, highly specialized needs is involved.

Furthermore, market demand and supply dynamics, geopolitical factors affecting raw material availability, and the regulatory compliance standards of the producing country all contribute to the final price. When seeking to purchase this intermediate, it is advisable to request detailed quotes from multiple suppliers, particularly from established chemical hubs like China, where competitive manufacturing environments exist. Understanding these pricing influences will enable you to effectively negotiate and secure the best value from your chosen supplier.
