Frequently asked questions

These compounds may lawfully be supplied in Great Britain as laboratory research materials. None of them holds a UK marketing authorisation, so they cannot be sold, described or supplied for human or veterinary use. Supplying an unlicensed product for human use is an offence under the Human Medicines Regulations 2012.

Purchasers must be 18 or over and must be buying for lawful laboratory or analytical research. We supply universities, contract research organisations, analytical laboratories and individual researchers working within that scope.

No. We do not publish dosing, reconstitution or administration information and we will not provide it on request. These materials are not supplied for use in humans or animals, so the question has no answer within the scope on which we supply.

No. No product on this site holds a UK marketing authorisation, and none has been assessed by the MHRA for safety, quality or efficacy in humans. Some compounds in this catalogue are authorised as medicines in other countries; that has no effect on their status in the United Kingdom.

Where a certificate has been released for the batch in stock, it is linked from the product record. Where it has not, the record shows the documentation as pending. We do not substitute a certificate from a different lot.

Because it is. A batch can be in stock before its analytical documentation has been released. We show that state explicitly rather than leaving a blank space, so you can decide before ordering whether to wait.

A certificate of analysis records what a specific batch was found to contain. A safety data sheet describes how to handle, store and dispose of the substance safely. They answer different questions and you may need both.

By lot number. The lot printed on the vial label must match the lot on the certificate. If they differ, the certificate describes different material. See batch lookup.

Compound name, catalogue number, pack size, physical form, technical identifiers including CAS number, molecular formula and molecular weight, the purity specification, storage conditions, and the documentation status for the current batch.

Yes, from established institutions. See For laboratories for quotations, PO terms and batch reservation.

Yes. Quantities above the catalogue pack sizes are quoted individually. Send the compound, total quantity and timeframe through the contact page.

The payment methods available to you are shown at checkout. Institutional buyers can be invoiced against a purchase order once an account is agreed.

The current UK target is 3 to 5 working days from order to delivery. Tracking is emailed when the parcel is handed to the carrier. Where an order is held pending batch documentation, we tell you before it ships.

Some destinations. Before ordering from outside the UK you must confirm that the material may lawfully be imported and held at the destination. Customs charges, delays and seizure are outside our control.

Photograph the damage at the point of delivery, before unpacking further, and contact us the same working day. See shipping and delivery.

As stated on the product record and on the vial label. Storage conditions are not the same across this catalogue, which is why they are listed per product rather than as a single site-wide statement.

Unopened, undamaged stock in its original sealed packaging may be returned within the window set out in the refund and returns policy. Once a seal is broken the material cannot be returned, because its integrity can no longer be established.
