MtoZ Biolabs offers Cellacefate Analysis Service to support detailed characterization and quality evaluation of this widely used pharmaceutical excipient. Also known as cellulose acetate phthalate, cellacefate is a pH-dependent polymer commonly employed as an enteric coating and release-controlling material in oral dosage formulations. Its ability to resist gastric acidity and dissolve under intestinal conditions makes it essential for achieving controlled drug delivery and ensuring patient safety.

Figure 1. Molecular Structure of Cellacefate
The performance of cellacefate depends on multiple parameters, including the degree of substitution, moisture level, viscosity, purity, and polymer uniformity. MtoZ Biolabs integrates advanced analytical technologies with standardized quality procedures to provide accurate, reproducible data that supports formulation optimization, regulatory compliance, and manufacturing consistency.
Services at MtoZ Biolabs
MtoZ Biolabs provides a comprehensive analytical platform for evaluating the chemical, physical, and functional characteristics of cellacefate. Each procedure follows validated laboratory protocols to ensure precision, reproducibility, and traceable results.
● Identification
FTIR spectroscopy is employed to compare the absorption spectrum of the sample against a certified reference standard. Distinct peaks corresponding to acetyl and phthaloyl functional groups confirm the polymer’s identity and chemical structure.
● Solubility and Viscosity Testing
Solubility is assessed in various organic solvents such as acetone and dioxane. Viscosity is measured using a calibrated viscometer after dissolution in an acetone–water mixture, providing insight into polymer chain integrity and processing behavior.
● Moisture and Volatile Content
Water content is determined using Karl Fischer titration or hydrometric analysis. Maintaining moisture levels below 5 percent ensures product stability and prevents hydrolysis during storage.
● Free Acid and Acetyl Group Determination
Acid–base titration methods accurately quantify the free acid content and acetyl substitution level, which are directly associated with coating performance and dissolution control.
● Heavy Metal and Residue Analysis
Residual metal content and inorganic residues are evaluated through incineration or ICP-based analysis to verify material purity and compliance with pharmaceutical safety standards.
● Thermal and Morphological Characterization
DSC and TGA analyses determine thermal stability and decomposition behavior, while SEM imaging provides a detailed evaluation of surface morphology, fiber structure, and particle uniformity.
● Functional Performance Testing
Dissolution and film-forming studies are performed in simulated gastric and intestinal fluids to evaluate enteric resistance, coating uniformity, and controlled-release performance.
This integrated analytical framework provides reliable data on identity, purity, and performance parameters to support research, process validation, and regulatory submissions.
