ChemSP - your B2B chemical sourcing brand. We provide consolidated logistics and multilingual technical support to ensure every shipment is stable and reliable.
Product Overview
ChemSP supplies aclarubicin free base to formulators, traders and research groups that need a documented, repeatable lot rather than an ad-hoc sample.
Its formula C42H53NO15 corresponds to 42 carbon atoms, 53 hydrogen atoms, 1 nitrogen atom and 15 oxygen atoms; that fixed ratio is what makes lot-to-lot equivalence testable rather than a matter of judgement.
The molecular weight of 811.9 makes it a comparatively large molecule, which generally means slower dissolution and a greater sensitivity to particle size.
Chemical Identity
| CAS Number | 57576-44-0 |
|---|---|
| Molecular Formula | C42H53NO15 |
| Molecular Weight | 811.9 |
| LogP (calculated) | 3.8 |
| Catalog Category | Pharmaceutical Intermediates & APIs |
Composition and Key Properties
Elementally the substance reads as a nitrogen- and oxygen-bearing framework (amide, amino acid or hydroxamate type).
The reported LogP of 3.8 is strongly oil-partitioning in character — relevant to extraction yields and to how much residue can be rinsed out of equipment.
Applications and Use Cases
aclarubicin free base (CAS 57576-44-0; formula C42H53NO15; 811.9 g/mol) is mainly applied in chemical synthesis, fine chemical manufacturing and related industrial processes. For specification, COA and bulk prices of aclarubicin free base, write to our sales team.
- Intermediate supply to API manufacturers where the specification is agreed against the downstream step.
- Analytical reference and small-scale evaluation before a supplier is qualified.
- Route scouting and process development ahead of a validated commercial synthesis.
Specific end-uses should be checked against your own regulatory assessment before the material is qualified in a finished product.
Packaging and Handling
Supplied in standard export packaging appropriate to the physical form of the material. The exact pack size, inner liner and net weight are fixed on the order acknowledgement, since they depend on whether the lot ships as a solid, a paste or a liquid. Customers with drum, liner or pallet constraints should specify them when enquiring.
Quality and Documentation
Each shipment is accompanied by a certificate of analysis covering identity (IR or NMR as applicable), assay, and the parameters agreed in the specification. A safety data sheet in the current GHS format is issued with the first order and reissued whenever the classification changes.
Supply and Quotation
To quote accurately we need the quantity, the destination, and the specification you intend to work to. Enquiries sent with those three details usually come back priced within one business day.
Frequently Asked Questions
What is the CAS number of aclarubicin free base?
The CAS registry number for aclarubicin free base is 57576-44-0. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Is aclarubicin free base a stock item or made to order?
Availability moves with the production schedule, so it is confirmed at the time of enquiry. For repeat volumes a scheduled call-off arrangement is usually preferable to one-off orders.
Can you supply aclarubicin free base with a specification we define?
Yes. The acceptance criteria can be adjusted within what the route allows — most often assay, moisture, heavy metals or particle size. Any change is written into the specification before the lot is released.

Extended Specifications
aclarubicin free base is supplied against a clear, batch-specific specification. When you request a quote, our team confirms the assay or purity grade, physical form, pack size and any residue limits relevant to your application. Typical parameters documented on the Certificate of Analysis include identity (CAS number), molecular formula, molecular weight, appearance, assay, loss on drying and heavy-metal limits where applicable.
Applications by Industry
Buyers source aclarubicin free base across food and beverage, nutraceutical and pharmaceutical, cosmetic and personal care, and selected industrial formulations. ChemSP aligns the grade and documentation set to the target application and destination market.
Regulatory & Compliance Support
ChemSP ships aclarubicin free base with a Certificate of Analysis for every batch and a Safety Data Sheet on request. Additional documentation such as specification sheets, third-party test reports and regulatory support letters is available to qualified buyers to streamline import, registration and quality-assurance workflows.
Storage & Handling
Store aclarubicin free base in a cool, dry, well-ventilated area in its original, tightly closed container, protected from moisture and direct sunlight. Follow the precautions in the Safety Data Sheet and standard chemical-handling guidance. Shelf life and re-test intervals are stated on the Certificate of Analysis.
Frequently Asked Questions
What is the minimum order quantity (MOQ)?
MOQ depends on grade and pack size. Sampling quantities typically start from 1 kg, with commercial volumes from 25 kg. Share your required volume and we will quote accordingly.
Can I request a sample and a Certificate of Analysis?
Yes. Samples and batch-specific Certificates of Analysis are available on request, and third-party testing can be arranged for qualified buyers.
What documentation supports import and registration?
Every shipment includes a Certificate of Analysis. The Safety Data Sheet, specification sheets and regulatory support letters are provided on request to support customs clearance and product registration in your market.
What are the typical lead times and payment terms?
Lead times vary with grade and volume. ChemSP quotes a firm delivery window with each offer, and standard international trading terms apply.

The table below is calculated from the molecular formula C42H53NO15. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains nitrogen (1 atoms). Nitrogen-bearing structures are often amine-like: they can absorb carbon dioxide from air and develop odour if the packaging is not tight.
A degree of unsaturation of 17 points to an aromatic or ring-containing skeleton.
Identity and Registry Data
- CAS number
- 57576-44-0
Handling, Storage and Stability
Protect from light and air. Unsaturated and aromatic structures tend to darken on oxidation, so opaque or inert-headspace packaging is preferred for long storage.
Store under ventilation with tightly closed packaging; amine-type nitrogen absorbs carbon dioxide from air and may develop odour.
Typical Specification Parameters
- Assay / content
- Loss on drying / moisture
- Appearance and odour
- Heavy metals (as Pb)
- Shelf life and packaging
These are the parameters normally reported on a certificate of analysis. Limits are lot-specific and follow the specification agreed between supplier and buyer; no numeric limits are stated or implied here.
