Micafungin Sodium Impurity Profile vs Tecoland: COA Benchmark
Related Substance Limits and Impurity Profiling: A Direct Comparison with Tecoland Micafungin Sodium
When evaluating Equivalent To Tecoland Micafungin Sodium, the impurity profile is the definitive benchmark for quality assurance. As a global manufacturer of pharmaceutical API, NINGBO INNO PHARMCHEM CO.,LTD. understands that QC managers require a seamless drop-in replacement that mirrors the reference product's safety and efficacy. Our micafungin sodium (CAS 235114-32-6) is produced under GMP standard conditions, with a focus on controlling related substances as per ICH guidelines. The primary impurities—such as the open-ring hydrolysis product (FR901379) and the des-acyl analog—are rigorously monitored. In our batch-specific COA, total impurities are consistently below 0.5%, with no single unknown impurity exceeding 0.10%. This aligns with the typical profile of Tecoland's material, ensuring identical chromatographic purity. A critical non-standard parameter we've observed in the field is the tendency of micafungin to form trace dimers under prolonged exposure to humidity, which can appear as a shoulder peak in HPLC. Our controlled drying process mitigates this, and we recommend storage below 25°C with desiccant to prevent such degradation.

Residual Solvent Thresholds and Class 2/3 Solvent Control in Micafungin Sodium Bulk Drug
Residual solvents are a critical quality attribute for any echinocandin antifungal API. Our micafungin sodium is manufactured using a synthesis route that minimizes Class 2 solvents, with acetone and ethyl acetate being the primary Class 3 solvents used. Per ICH Q3C, limits are set at 5000 ppm for acetone and 5000 ppm for ethyl acetate, and our typical batches show levels below 1000 ppm. This is comparable to Tecoland's specifications. A field-experience insight: during winter shipping, residual solvent levels can appear elevated in headspace GC analysis if the sample is not equilibrated properly due to cold-induced viscosity changes. We advise equilibrating samples at 25°C for at least 2 hours before testing. Our bulk price includes a comprehensive residual solvent report, ensuring transparency for your regulatory filings.
HPLC Method Validation: Peak Tailing Anomalies and Resolution of Hydrolysis Byproducts
Method transfer is often the most challenging aspect when switching to an Equivalent To Tecoland Micafungin Sodium. Our HPLC method, validated per USP <1225>, uses a C18 column with a phosphate buffer-acetonitrile gradient. The main peak typically elutes at 12.5 minutes, with the hydrolysis byproduct (FR901379) at relative retention time 0.85. A common anomaly is peak tailing for the main component, which can exceed 2.0 if the column temperature is not controlled at 30°C. We have found that using a column with high-purity silica and end-capping reduces tailing to below 1.5. Additionally, the resolution between micafungin and its des-acyl analog must be at least 2.0. Our COA includes system suitability parameters to facilitate smooth method transfer. For handling issues that may affect sample integrity, see our guide on preventing electrostatic clumping during winter shipping of micafungin bulk powder.
Chromatographic Resolution Strategies for Micafungin Sodium to Meet Pharmacopeial Monographs
Meeting pharmacopeial monographs (USP, EP) requires robust chromatographic resolution. Our micafungin sodium is tested against the USP Micafungin Sodium monograph, which specifies limits for related compound A (FR901379) at NMT 0.5% and any other individual impurity at NMT 0.2%. We achieve this through a combination of high-purity starting materials and optimized purification. A non-standard parameter we monitor is the presence of a late-eluting impurity at RRT 1.8, which can be a dimer formed during storage. By controlling the API's water content below 2%, we suppress this impurity. The table below compares our typical impurity profile with the expected Tecoland profile based on publicly available information.
| Parameter | INNO Pharmchem Micafungin Sodium | Tecoland Micafungin Sodium (Typical) |
|---|---|---|
| Assay (anhydrous basis) | 98.0-102.0% | 98.0-102.0% |
| Total Impurities | ≤0.5% | ≤0.5% |
| FR901379 (Hydrolysis) | ≤0.3% | ≤0.3% |
| Des-acyl analog | ≤0.2% | ≤0.2% |
| Any unknown impurity | ≤0.10% | ≤0.10% |
| Residual solvents (Class 3) | <1000 ppm | <1000 ppm |
| Water content | ≤2.0% | ≤2.0% |
This performance benchmark ensures that our product can be used as a direct substitute without revalidation of analytical methods.
Bulk Packaging and Stability Considerations for Micafungin Sodium API
Our micafungin sodium is packaged in double-layer LDPE bags inside aluminum foil pouches, with desiccant, and then placed in fiber drums. This packaging is equivalent to industry standards and protects the API from moisture and light during transit. We offer quantities from 100g to 25kg, with larger orders shipped in 210L drums. Stability studies under ICH conditions (25°C/60% RH and 40°C/75% RH) show no significant change in impurity profile over 24 months. A field note: in sub-zero temperatures, the powder may exhibit increased electrostatic charge, leading to clumping. This does not affect quality but can be mitigated by grounding containers before opening, as detailed in our handling guide. Our high purity micafungin sodium is a reliable research chemical and production API for Mycamine generic formulations.
Frequently Asked Questions
What are the impurities in micafungin?
The primary impurities in micafungin sodium include the open-ring hydrolysis product (FR901379), the des-acyl analog, and potential dimeric forms. These are controlled to pharmacopeial limits, with total impurities typically below 0.5%.
What is another name for micafungin?
Micafungin is also known by its research code FK463 and the brand name Mycamine. The CAS number is 235114-32-6.
Is micafungin the same as meropenem?
No, micafungin is an echinocandin antifungal, while meropenem is a carbapenem antibiotic. They have different mechanisms of action and therapeutic uses.
Is micafungin better than fluconazole?
Micafungin and fluconazole belong to different antifungal classes. Micafungin is often preferred for invasive candidiasis due to its fungicidal activity and lower resistance rates, but the choice depends on the fungal species and patient factors.
