Intermediates

Carbon-14 labelled Intermediates for Synthesis

As part of the Quotient Amersham* Radiochemicals Service we can supply a number of ¹⁴C-labelled substrates, which are suitable as intermediates for radiochemical synthesis.

These intermediates are typically available in quantities from 25mCi to 300mCi, although quotes can be provided for smaller and larger quantities.

These compounds are provided at the specifications given below normally within 2 to 5 weeks of receipt of order.
