In the pharmaceutical industry, the quality of every component, from the final API to the smallest intermediate, is non-negotiable. (R)-3-Chloro-1-phenylpropanol (CAS 100306-33-0) is a prime example of a chemical intermediate where stringent quality control and precise specifications are paramount. Its role as a building block in the synthesis of critical medications, particularly antidepressants, demands a high level of purity and chemical integrity. NINGBO INNO PHARMCHEM CO.,LTD. is committed to ensuring that our supply of this intermediate meets the highest industry standards.

The Importance of Purity in Pharmaceutical Intermediates

The synthesis of complex pharmaceutical molecules often involves multi-step processes. Each step requires intermediates that are free from significant impurities that could interfere with subsequent reactions, reduce yields, or, most critically, be carried through to the final drug product. For (R)-3-Chloro-1-phenylpropanol, a common specification is a purity assay of u226598.0%. This percentage refers to the amount of the desired chemical compound present, with any deviation potentially impacting downstream processes. Buyers should always request a detailed Certificate of Analysis (CoA) from their supplier to verify this critical parameter.

Key Specifications and Analytical Methods

Beyond the overall purity assay, specific parameters for (R)-3-Chloro-1-phenylpropanol are vital for its use in pharmaceutical synthesis. These can include:

  • Appearance: Typically described as a white to light yellow powder, indicating its physical form and general visual quality.
  • Enantiomeric Purity (ee): For chiral intermediates, the enantiomeric excess is crucial. While not always explicitly stated in basic specifications, it's often implied by the specific chiral designation ((R) in this case) and can be verified through chiral chromatography.
  • Water Content: Moisture can affect the stability and reactivity of chemicals, so low water content is often a requirement.
  • Residual Solvents: Manufacturing processes often use solvents, and residual amounts must be controlled to meet regulatory limits.
  • Specific Impurities: Identification and quantification of known process-related impurities or degradation products are also critical.

Analytical techniques such as High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Mass Spectrometry (MS), and Nuclear Magnetic Resonance (NMR) are employed by reputable manufacturers to confirm these specifications.
