Betadex Sulfobutyl Ether Sodium—also known as SBECD, Sulfobutylether-β-cyclodextrin, and Captisol®—is the active excipient behind some of the most innovative injectable and parenteral drug formulations in modern medicine. As a highly water-soluble, anionic derivative of β-cyclodextrin produced by introducing sulfobutyl ether groups, SBECD has emerged as the preferred solubilizing excipient for parenteral drug delivery, with an unparalleled record of safety, efficacy, and regulatory acceptance.

SBECD is available in multiple grades:

  • Injectable Grade — for parenteral formulations, with strict endotoxin control (≤20 EU/g)

  • Pharmaceutical Grade (Oral) — for tablets, capsules, and oral liquids

  • Nutraceutical Grade — for dietary supplements and functional foods

  • Cosmetic Grade — for skincare and personal care formulations

  • Research Grade — for analytical and preclinical applications

Bulk Betadex sulfobutyl ether sodium Powder is a white to off-white crystalline powder.

It is one of the most popular excipients ever used in our pharmaceutical industry, especially for injections.

It is amorphous and hygroscopic.

It is freely soluble in water and slightly soluble in methanol but insoluble in ethanol, ethyl acetate, and dichloromethane.

Its solubility in 100ml water is more than 50g, the pH of its 30% water solution is 5.4~6.8.

It is an improved version of hydroxy beta-cyclodextrin, with better complexation performance but at a higher price.

What Is SBECD Used For?

Sulfobutyl-β-cyclodextrin is an anionic cyclodextrin derivative with better water solubility.

It will form a non-covalent complex with many APIs (water-insoluble) to improve and optimize API properties.

The SBECD & Heparin complex exhibits biological activity similar to heparin but with lower nephrotoxicity, so SBECD is widely used as a high-end injection carrier.

SBECD will make APIs more stable and more readily soluble in water for injection. It will also lower their renal toxicity and reduce their chances of hemolysis.

We also use SBECD to control the release rate of active ingredients while covering API odors and bitter tastes.

Studies have shown that about 40% of new APIs are insoluble in water, and nearly 60% have poor water solubility.

Due to their poor water solubility, clinical trials of new drugs are less effective than expected.

This poor water solubility has significantly slowed the approval of these new molecules as new drugs.

Therefore, many pharmaceutical manufacturers have widely used Sulfobutyl-β-cyclodextrin sodium to improve the solubility of poorly water-soluble APIs, thereby enabling many new drugs to be approved.

When we mix docetaxel with sulfobutyl-β-cyclodextrin sodium at a molar ratio of 1:12, the solubility of docetaxel in water increases by about 800-fold, enabling the development of docetaxel water injections.

When we tested the water solubility of the complexed compound between sodium calycetin (Another API) and sulfobutyl-β-cyclodextrin sodium, we increased its water solubility by about 76-fold.

After we mix Amiodarone (API name) with sulfobutyl-β-cyclodextrin sodium at a molar ratio of 1:2, we increase the solubility of the complex in water by 195-fold.In In In 

2020, we had COVID-19; Remdesivir is formulated as an injection by combining betadex sulfobutyl ether sodium.

Though it is an excellent injection carrier, no pharmaceutical company should abuse it.

According to scientific research, the maximum daily dosing is 320 mg/kg.

How To Ship And Store SBECD Powder?

For shipping SBECD, you can ship it by sea if you purchase it in commercial order quantities.

We can ship small quantities either by courier or by air for you.

It is a very safe chemical suitable for air shipment. Its certificate of safe air transportation is available.

During the transport, you don’t need ice bags or cold-chain storage. It is stable at RT.

sulfobutyl-β-cyclodextrin must be stored in an airtight inner package and protected from light.

Because it is hygroscopic and readily draws moisture from the air, water can compromise its quality if it is not sealed well.

Though it is relatively stable, store it in a firm container protected from heat and light.

You can store it at room temperature, ensuring there is no significant temperature fluctuation.

It has a shelf life of 2 years. Make sure you run tests before you use them.

How Much Does SBECD Cost?

If you need to buy its injection-grade pure powder in commercial order quantities to manufacture injections, our FOB Shanghai/Beijing price is around 350~500 USD/Kilo.

If you only need kilos for pilot trials, our price is around 600 USD per kg.

If you need several grams for lab research and testing, we promise you the best quality at the lowest prices.

In case you are not sure if you are getting a reasonable price from us, you can check some of our online prices below:

sbecd price from sigma is 414usd for 500mg
SBECD cost from sigma is about 400usd per 500mg
sbecd price from cymit is 421euros for 500mg
sbebcd price from cymit is 421euros for 500mg

As you can see from the reagent company’s offers, the price per 0.5g is higher than the cost of one kilo from us, not to mention the per-gram prices.

If your lab doesn’t have sufficient budget, give us a chance—you won’t regret it.
