Synthon-Lab has a database of more than 6000 unique and diverse building blocks and intermediates. One part of compounds (marked in our database as "in stock") is available from our stock in range of 1 to 20 g and can be delivered within 1–2 weeks. The other part (marked in our database as "order") can be synthesized on demand and supplied within 2–6 weeks.

You can alternatively analyze overall set of our compounds in cumulative database.

Even if you can not find your particular compound in our databases we will be pleased to help you in your work. Having a wide experience in organic synthesis Synthon-Lab can synthesize especially for you exactly those building block or intermediate that you need. For example we call your attention to a list of common structures of different classes which are easily accessible for us. If you are interested in these or analogous compounds, we can offer you fast and cost-effective solutions.

• Carboxylic acids
• Carbonyl chlorides
• Sulfonyl chlorides
• Aldehydes and ketones
• α-Haloketones and benzyl-type halides
• Alkyl and aryl halides
• Amines
• Thiols
• Alcohols
