For any pharmaceutical manufacturer, the procurement of chemical intermediates is a process that demands meticulous attention to detail, especially concerning product specifications. Methyl 2-cyclopropyl-4-(4-fluorophenyl)quinoline-3-carboxylate (CAS: 121659-86-7) is a prime example of an intermediate where quality directly translates to the efficacy and safety of the final drug product, Rosuvastatin Calcium. This article guides procurement managers and research scientists on what specifications to prioritize when looking to buy this crucial compound.

The most critical specification for any pharmaceutical intermediate is its purity. For Methyl 2-cyclopropyl-4-(4-fluorophenyl)quinoline-3-carboxylate, an assay of ≥98.0% is generally considered the benchmark for effective use in API synthesis. Impurities, even in small amounts, can lead to unwanted side reactions, complicate purification processes, and potentially compromise the quality of the final Rosuvastatin Calcium. Therefore, when inquiring about pricing or quantities from a manufacturer, always confirm the stated purity and the analytical methods used for its determination.

Beyond purity, the physical characteristics of the intermediate are also important. The typical appearance of this compound is a white to yellow crystalline powder. Consistency in appearance can be an indicator of consistent manufacturing processes and purity. Other key parameters provided by reputable suppliers often include loss on drying (≤1.0%), which relates to the residual moisture content, and detailed physical properties like boiling point and density, which are important for process engineering and handling. Understanding these details helps buyers make informed decisions when selecting a supplier.

For businesses aiming to buy this intermediate, especially in bulk, partnering with a reliable manufacturer in China offers significant advantages. NINGBO INNO PHARMCHEM CO.,LTD. operates with a commitment to quality and consistency, ensuring that our supply meets the stringent requirements of the pharmaceutical industry. We provide detailed technical data sheets and are transparent about our manufacturing processes. When you request a quote, you can expect comprehensive information regarding these essential specifications.

Furthermore, packaging and storage conditions are vital for maintaining the integrity of the chemical intermediate. Typically supplied in 25 kg drums, or as per customer requirements, proper storage in a cool, ventilated place is crucial. By prioritizing these specifications and working with trusted suppliers like ourselves, pharmaceutical companies can secure a high-quality, reliable source of Methyl 2-cyclopropyl-4-(4-fluorophenyl)quinoline-3-carboxylate, thereby ensuring the efficient and successful production of Rosuvastatin Calcium.
