British Pharmacopoeia Chemical reference substances (BPCRS)

These Primary standards are established using absolute methods and the declared content figures are determined without comparing to another substance. You should use BPCRS to perform the tests in the British Pharmacopoeia (BP) or BP (Veterinary). Do not eat BPCRS or feed them to animals – you should only use BPCRS for chemical analysis. They are not suitable for any other use.

The BPCRS Catalogue is now available for download in Excel format, updated monthly to reflect the latest listings.

New customer rules in Egypt

New customs rules in Egypt means additional actions are required by purchasers of the BPCRS if your order is over the value of £1600 or the shipment weighs more than 50kg. Please refer to the Egypt shipments guidance to learn what steps you will need to take if your order meets this criteria.
