The pharmaceutical industry relies on a complex chain of chemical synthesis, where each intermediate plays a crucial role in producing effective medications. 1,2-Cyclohexanedicarboximide (CAS: 7506-66-3) is one such indispensable compound, serving as a vital building block in the manufacturing of important pharmaceuticals. This article explores its significance, chemical attributes, and the importance of sourcing it from reliable manufacturers and suppliers.

Understanding 1,2-Cyclohexanedicarboximide: Key Properties

1,2-Cyclohexanedicarboximide is identified by its chemical name cis-Hexahydro-1H-isoindole-1,3(2H)-dione and is commonly presented as a white crystalline powder. Its molecular formula is C8H11NO2, with a molecular weight of approximately 153.178. Key physical properties include a density of 1.18 and a boiling point of 330.8ºC. Critically for pharmaceutical applications, it typically exhibits an assay of ≥98.0% and a low loss on drying (≤1.0%). These specifications ensure a high degree of purity and consistency, which are non-negotiable requirements in pharmaceutical production.

A Crucial Intermediate for Perospirone

The primary and most significant application of 1,2-Cyclohexanedicarboximide in the pharmaceutical sector is its role as a precursor in the synthesis of Perospirone. Perospirone is a widely used atypical antipsychotic medication, prescribed for conditions such as schizophrenia. The manufacturing process for Perospirone requires high-purity intermediates to ensure the final drug's safety, efficacy, and stability. For pharmaceutical companies, sourcing 1,2-Cyclohexanedicarboximide from a trusted manufacturer is paramount. This ensures that the synthesis pathway remains robust and that the final API meets all regulatory and quality standards.

Importance of Purity and Quality Control

In pharmaceutical manufacturing, the quality of intermediates directly impacts the quality of the final drug product. Therefore, the ≥98.0% assay and low loss on drying of 1,2-Cyclohexanedicarboximide are not merely technical specifications; they are critical quality indicators. R&D scientists and production managers must ensure that the 1,2-Cyclohexanedicarboximide they purchase consistently meets these standards. Working with suppliers who provide comprehensive Certificates of Analysis (CoA) is essential for quality assurance and regulatory compliance.

Sourcing Strategies: Working with Suppliers

When seeking to buy 1,2-Cyclohexanedicarboximide, particularly for large-scale pharmaceutical production, identifying reliable suppliers is key. Manufacturers in China are significant players in the global supply of such intermediates, often offering competitive pricing and substantial production capacities. Procurement professionals should look for suppliers who can demonstrate adherence to international quality management systems, provide consistent product quality, and offer stable supply chains. Furthermore, inquiring about packaging options, such as the standard 25 kg/drum, and potential for custom packaging can streamline logistics.

By partnering with reputable chemical manufacturers and suppliers, pharmaceutical companies can secure the high-purity 1,2-Cyclohexanedicarboximide necessary for their manufacturing processes, ultimately contributing to the successful production of essential medications like Perospirone.
