N-Acetyl-L-Phenylalanine Drop-In Replacement For Sigma
N-Acetyl-L-Phenylalanine Purity Grades: 99.0%–99.5% HPLC Assay Specifications for Industrial Formulations
NINGBO INNO PHARMCHEM CO.,LTD. manufactures N-Acetyl-L-Phenylalanine (CAS: 2018-61-3) with strict assay controls to support high-precision industrial applications. The standard industrial grade maintains an HPLC assay between 99.0% and 99.5%. This assay window is critical for ensuring consistent stoichiometry in peptide synthesis and nutraceutical formulations. As a key L-Phenylalanine derivative, the product requires precise enantiomeric purity to prevent racemization during downstream processing steps. We utilize high-resolution chromatography to verify the Ac-Phe-OH content, ensuring batch-to-batch reproducibility that procurement teams can rely on for production planning.
Deviations outside this assay range can impact reaction yields in solid-phase peptide synthesis (SPPS) and alter the final product profile in dietary supplements. Our manufacturing process controls the acetylation step to minimize byproduct formation, preserving the structural integrity of the molecule. The 99.0%–99.5% specification aligns with the requirements for both pharmaceutical intermediates and high-grade nutraceutical ingredients. Please refer to the batch-specific COA for exact assay values per lot, as minor variations may occur within the specified range depending on the synthesis batch.
Certificate of Analysis (COA) Parameters: Heavy Metal Thresholds, Residual Solvent Limits, and Chromatographic Purity Metrics
Quality assurance protocols mandate rigorous testing for impurities to ensure product safety and performance. The Certificate of Analysis (COA) details heavy metal thresholds, typically monitored via ICP-MS, and residual solvent limits aligned with ICH guidelines. Manufacturing adheres to GMP standard principles to maintain consistency across production runs. Chromatographic purity metrics include related substance profiling to detect N-Acetyl-3-phenyl-L-alanine dimers, hydrolysis byproducts, or incomplete acetylation residues. Trace impurities can catalyze discoloration during high-temperature processing or interfere with downstream purification; our quality control isolates these variables to prevent formulation failures.
The COA provides a comprehensive chromatogram overlay demonstrating peak symmetry and resolution. Related substances are quantified to ensure they remain below detection limits that could impact the final application. For applications requiring ultra-high purity, we offer grades with tightened impurity profiles. Procurement and R&D managers should review the COA for specific numerical limits on heavy metals, residual solvents, and related substances, as thresholds may vary based on the intended application grade. Please refer to the batch-specific COA for the complete chromatographic data and impurity list.
Direct Drop-in Replacement for Sigma: Molecular Weight, Melting Point Range, and Specific Optical Rotation Benchmarks

Field Engineering Note: During winter shipping, N-Acetyl-L-Phenylalanine can exhibit transient caking due to moisture migration within the drum headspace, even when sealed. This is a physical phenomenon, not a chemical degradation. Our engineering recommendation is to allow the material to equilibrate to ambient temperature for 24 hours before opening the drum. If caking occurs, gentle mechanical agitation restores flowability without impacting the HPLC assay or optical purity. This behavior is distinct from hygroscopic deliquescence and does not require desiccant intervention during storage. Monitoring thermal degradation thresholds is also critical; prolonged exposure to temperatures exceeding 120°C during processing can initiate deacetylation. We recommend maintaining processing temperatures below 100°C to preserve the acetyl group integrity.
Bulk Packaging & Logistics Specifications: 25kg Nitrogen-Flushed Composite Drums and IBC Container Compliance Standards
Packaging specifications are designed for stability and handling efficiency. Standard bulk shipments utilize 25kg nitrogen-flushed composite drums to minimize oxidative exposure and moisture ingress. Nitrogen flushing displaces oxygen, reducing the risk of oxidation during transit and storage. For larger tonnage, IBC containers are available, compliant with standard transport regulations. As a global manufacturer, we optimize logistics to reduce lead times and ensure timely delivery. Packaging integrity is verified prior to dispatch, including seal checks and drum pressure testing. Bulk price structures are tiered based on volume commitments, offering significant cost savings for long-term contracts. Acetyl-L-phenylalanine shipments are routed through established logistics channels to maintain supply chain continuity. Please refer to the technical data sheet for detailed packaging dimensions and weight specifications.
