13C Molecular was founded to serve the growing demand from the pharmaceutical and bio-medical community for stable isotope labeled, custom synthesized organic compounds.   The business has grown to include an analytical services division and custom catalog of labeled reference standards.

As our name suggests, we specialize in producing 13C labeled compounds.   At 13C Molecular our highly experienced chemists, all PhD’s, have worked with clients from around the world providing consistently sound service in the stable isotope molecular chemistry field.  We also have 2H (d), 15N and 18O heavy labeled compounds.

We are a small company where the mission imperative is client satisfaction.  Our team do not clock-in to work, we do not have a scheduled work week, but rather we work when the job requires it.   This provides optimum flexibility to serve our client needs.
