Safety information

Every possible precaution should be taken when handling, using, storing or disposing of any material supplied by Carbosynth. So far as we are able, we will provide all possible advice and assistance to customers concerning the safe handling of our products. For any material, the potential hazards are not always known and an absence of warning does not mean that no hazard exists. It is the users’ responsibility to ensure that relevant safety precautions are taken at all times


Many of our products are refrigerated or frozen for long-term storage. Short periods at higher temperatures (less than 1 week), as might occur during shipping, should not affect product life or efficacy

Chemical purity and Product grades

Carbosynth Bioscience products are supplied in two different grades:- Bio-X grade and Research Grade

Bio-X grade products are identified on the website and in our literature by the Bio-X logo.  They are our pre-eminent products and meet the highest standards of chemical purity, typically > 99% by HPLC. Purity is assessed using an array of techniques including HPLC, chiral HPLC, NMR, microanalysis, melting point, optical rotation, TLC, and mass spectrometry. All data is kept on file and available for inspection on request.  Bio-X grade products are also supported by up to date literature and carefully defined solubilty protocols, and are backed up by a comprehensive technical support service

Research Grade

Research grade products are supplied to the same high quality standards as Bio-X products but may not always be supported with the same details or the levels of literature references or solubility protocols.  Nonetheless, they are still suitable for biochemical applications


Carbosynth Bioscience product solubility is reported in a range of solvents.  As these compounds are intended for use in biological systems, we present the most water soluble conditions that we can determine.   If we state DMSO or ethanol as solvent then we will have found the compound to be too insoluble in other solvents to give a value.  However, once a stock solution is made in DMSO or ethanol it is usually possible to add water or buffer to this to further dilute it

We make a range of statements about the solubility of our Bioscience products and an explanation of each follows:

Soluble in water to 100mM - the product is freely soluble in water

Soluble in water to 10mM - the product is easily soluble in water up to a concentration of 10 mM.  It is not readily soluble in water at a higher concentration than this

Soluble in 1eq NaOH to 100mM - the product is freely soluble in 1M sodium hydroxide solution

Soluble in DMSO to 100mM - the product is freely soluble in DMSO

When making up solutions, if a small amount of material is left over, try shaking and/or warming it, to a maximum of 40°C


Due to the novelty of many of our products, information concerning product stability, particularly in solution, is not often known and in most cases we can only offer a general guide. When information is known we do our best to publish this on our website and data sheets.  Our standard recommendations are as follows:

Storage of solids: Provided storage is as stated on the product MSDS and the vial is kept tightly sealed, the product can be stored for up to 6 months

Solutions: We recommend that stock solutions, once prepared, are stored in tightly sealed vials at -20°C. Generally these will be useable for up to one month. Wherever possible solutions should be made up and used on the same day

Before use it is recommended that the product be allowed to equilibrate to room temperature for at least 60 mins

Stock solutions should be made up using the batch specific molecular weight of the product
