Triclosan Equivalent For Sigma-Aldrich 72779 | High Purity
Matching Technical Specifications for Sigma-Aldrich 72779 Triclosan
Procurement teams requiring a drop-in replacement for catalog number 72779 must validate physical and chemical parameters against strict internal standards. The target molecule, chemically identified as 5-chloro-2-(2, 4-dichlorophenoxy)phenol, requires consistent assay values to ensure formulation stability. NINGBO INNO PHARMCHEM CO.,LTD. manufactures batches that align with the performance benchmark set by legacy catalog items, focusing on purity profiles rather than brand labeling.
Critical physical properties include a melting point range of 54.0°C to 57.0°C and a characteristic phenolic odor. The appearance should be white to off-white crystalline powder. Deviations in color or particle size distribution can impact dissolution rates in solvent systems such as ethanol or propylene glycol. Our production lines utilize recrystallization processes to minimize colored impurities, ensuring the material meets the visual and tactile expectations of R&D laboratories transitioning from previous supply sources.
The following table outlines the comparative technical specifications required for qualification:
| Parameter | Standard Specification | Typical Result |
|---|---|---|
| Assay (HPLC) | ≥ 99.0% | 99.5% |
| Melting Point | 54.0°C - 57.0°C | 55.5°C |
| Loss on Drying | ≤ 0.5% | 0.3% |
| Residue on Ignition | ≤ 0.1% | 0.05% |
| Heavy Metals (as Pb) | ≤ 10 ppm | < 5 ppm |
These metrics ensure the material functions effectively as an antibacterial additive without introducing variability into downstream processes. Consistency in batch-to-batch analysis is prioritized over marginal cost reductions that might compromise purity.
Verifying CAS 52320-91-1 Purity in Triclosan Equivalents
Accurate chemical identification is fundamental when sourcing equivalents. While the header references distinct CAS registries, it is imperative to confirm that the supplied material corresponds to CAS 3380-34-5 for Triclosan applications. Confusion often arises between chlorophenol derivatives, such as Triclocarban (52320-91-1), and Triclosan. Analytical verification must distinguish these entities to prevent formulation errors.
Verification protocols utilize Gas Chromatography-Mass Spectrometry (GC-MS) and High-Performance Liquid Chromatography (HPLC). GC-MS provides fingerprinting capabilities to detect structural analogs or isomers that may co-elute during simpler analyses. The presence of related substances, such as dichlorophenol or monochlorophenol residues from synthesis, must be quantified. Limits for these impurities are typically set below 0.5% individually and 1.0% collectively.
Identity confirmation also involves infrared spectroscopy (FTIR). The spectrum should match the reference standard for 5-chloro-2-(2, 4-dichlorophenoxy)phenol within defined tolerance limits. R&D teams should request raw chromatograms alongside the summary COA to validate peak resolution and retention times. This level of scrutiny ensures that the equivalent material performs identically to the reference standard in antimicrobial efficacy testing.
Securing Certificate of Analysis for R&D Grade Triclosan
Obtaining a comprehensive Certificate of Analysis (COA) is a non-negotiable step in the qualification process. The document must originate directly from the quality control department of the global manufacturer and include specific test methods rather than generic pass/fail statements. NINGBO INNO PHARMCHEM CO.,LTD. provides batch-specific documentation detailing the analytical procedures used, such as USP or EP methods where applicable.
Key data points on the COA should include quantitative results for assay, melting point, and impurity profiles. For R&D applications, additional data on residual solvents is critical. Solvents like toluene or methanol used during synthesis must be reported according to ICH Q3C guidelines, even if full regulatory compliance documentation is not the primary focus. This transparency allows formulators to assess safety margins for specific end-use applications.
For teams developing personal care or hygiene products, understanding how these specs integrate into final products is essential. You may refer to our Triclosan Formulation Guide For Antibacterial Soap 2026 to align raw material specifications with finished product stability requirements. This ensures that the high-purity material sourced maintains efficacy throughout the product shelf life.
Navigating Regulatory Compliance for Triclosan Procurement
Procurement strategies must account for varying regional restrictions on antimicrobial agents. While this document does not address specific regulatory registrations, buyers must verify that the material meets the quality specifications required for their target market. Documentation such as Safety Data Sheets (SDS) should be reviewed for hazard classifications and handling instructions.
Quality specifications often serve as the primary control measure in the absence of specific regulatory claims. Parameters like heavy metal content and microbial limits are critical for industrial grade and laboratory-grade materials. Suppliers should provide evidence of testing for Salmonella, E. coli, and Staphylococcus aureus to ensure the raw material itself does not introduce bioburden into sterile or low-bioburden manufacturing environments.
Transparency regarding synthesis routes is also valuable. Knowing whether the material is synthesized via etherification of chlorophenols allows chemists to anticipate potential byproducts. This information aids in risk assessment for impurity carryover. Buyers should request written confirmation of the manufacturing process flow to ensure alignment with their internal quality assurance protocols.
Cost-Effective Sourcing Options for Laboratory-Grade Triclosan
Bulk synthesis offers significant cost advantages over small-scale catalog purchases. Direct sourcing from the manufacturer eliminates distributor markups and provides greater control over lead times. For laboratories requiring consistent supply of preservative solution components or solid active ingredients, negotiating annual supply agreements based on projected volume is recommended.
Pricing models typically vary based on purity grade and packaging. Standard industrial grade material may be supplied in 25kg fiber drums, while high-purity R&D grades might be packaged in smaller aluminum foil bags within cartons to prevent moisture uptake. Custom packaging options are available to suit specific handling requirements within the laboratory or production facility.
