As a supplier of specialized pharmaceutical intermediates, we understand that precision and clarity are paramount for our clients. For (R)-2-((4-Aminophenethyl)amino)-1-phenylethanol Hydrochloride, identified by CAS number 521284-22-0, its role as a key intermediate in Mirabegron synthesis demands strict adherence to specific quality parameters. When purchasing this compound, procurement managers and R&D scientists must prioritize these critical specifications to ensure successful downstream API production.

The most fundamental specification is the appearance. Our product typically presents as a white to off-white crystalline powder. Deviations from this can indicate potential contamination or degradation, underscoring the importance of visual inspection and relying on reputable manufacturers. Consistency in appearance is a good first indicator of reliable production processes.

Next, the assay, often determined by High-Performance Liquid Chromatography (HPLC), is crucial. We guarantee an assay of ≥98.0%. This metric directly reflects the proportion of the desired compound in the material. For pharmaceutical intermediates, higher assay values are essential to minimize the introduction of impurities into the synthesis pathway, which can complicate purification and impact the final API's quality.

Equally critical, especially for chiral molecules like this intermediate, is the chiral purity. Our (R)-2-((4-Aminophenethyl)amino)-1-phenylethanol Hydrochloride boasts a chiral purity of ≥99.0%. This ensures that the desired enantiomer is predominantly present, which is vital for the stereoselective synthesis of Mirabegron. Impurities of the undesired enantiomer can lead to reduced efficacy or unwanted side effects in the final drug product.

Other important specifications include Loss on Drying (LOD), which is kept to ≤1.0% to manage moisture content and ensure accurate weighing, and Total Impurities, which we maintain at ≤2.0%. These parameters, alongside molecular weight (292.804 g/mol) and molecular formula (C16H21ClN2O), provide a comprehensive profile of the product. When you buy from us, you are assured of materials that meet these exacting standards, enabling your R&D and manufacturing processes to proceed with confidence. We aim to be your trusted supplier for high-quality pharmaceutical intermediates.
