In the realm of pharmaceutical development and manufacturing, the quality of raw materials and intermediates directly dictates the success of the final Active Pharmaceutical Ingredient (API). For compounds like 4-Chloro-2,3-dihydroisoindol-1-one, a crucial intermediate for Lenalidomide synthesis, understanding and verifying its purity and specifications is not just good practice – it's a necessity. This guide is tailored for R&D scientists and quality control professionals who require in-depth knowledge about sourcing high-grade chemical intermediates.
The chemical name, 4-Chloro-2,3-dihydroisoindol-1-one, and its CAS number, 871723-37-4, are the first identifiers for procurement. However, the true value of this intermediate is revealed in its specifications. A typical requirement is an assay of ≥98.0%. This percentage indicates the minimum amount of the target compound present in a sample. For pharmaceutical applications, higher assays are generally preferred to minimize the introduction of unwanted byproducts into the synthesis chain.
Beyond the primary assay, other critical specifications for 4-Chloro-2,3-dihydroisoindol-1-one include:
For R&D scientists planning synthesis routes, knowing these specifications allows for accurate stoichiometric calculations and prediction of reaction outcomes. Quality control professionals rely on these parameters to verify incoming materials, ensuring they meet the stringent standards required for pharmaceutical manufacturing. When sourcing from a chemical supplier or manufacturer, always request a detailed Certificate of Analysis (CoA) that clearly outlines these specifications.
The global market offers various sources for 4-Chloro-2,3-dihydroisoindol-1-one, with manufacturers in China being prominent. However, it is crucial to vet potential suppliers thoroughly. Beyond specifications, consider their manufacturing capabilities, regulatory compliance, and track record. For bulk purchases, comparing prices while maintaining a focus on quality assurance is essential. Partnering with a manufacturer who understands the critical nature of pharmaceutical intermediates ensures that your supply chain is robust and reliable, allowing your R&D efforts to proceed with confidence.
