Description

Cellulose Tris-3,5-Dimethylphenyl-Carbamate is a high-purity, derivatized polysaccharide widely used as a chiral stationary phase (CSP) in high-performance liquid chromatography (HPLC). This compound matters for its exceptional ability to separate enantiomers, which is critical for ensuring the purity, safety, and efficacy of chiral pharmaceuticals and fine chemicals. It is primarily needed by analytical laboratories, R&D centers, and production facilities in the pharmaceutical, agrochemical, and biotechnology industries for chiral analysis and purification.

Application

• Chiral Chromatography: As a key component in chiral HPLC columns for the analytical and preparative separation of enantiomers.
• Pharmaceutical Development: For the purity testing, method development, and quality control of chiral active pharmaceutical ingredients (APIs) and intermediates.
• Agrochemical Analysis: Enantiomeric separation of pesticides, herbicides, and fungicides to study their biological activity and environmental impact.
• Academic & Industrial Research: A versatile tool in synthetic chemistry and biochemistry for studying stereoselective reactions and isolating pure enantiomers.
• Fine Chemical Purification: Used in the purification of chiral flavors, fragrances, and other specialty chemicals.
• Regulatory Compliance Testing: Supporting compliance with pharmacopeial standards (USP, EP) that require enantiomeric purity assessment.
