3-Bromcamphor is camphor derivative, that used in Russia as a calming agent and an indirect anticoagulant in the form of tablets based on both left-hand-rotating and racemic isoforms of this compound. The use of racemic bromcamphor instead of the optically active forms is explained by the much (almost tenfold) lower cost at a comparable physiological activity of the former drug. Racemic bromcamphor has a lower melting point as compared to that of the left-hand-rotating isomer (48 – 53°C versus 71 – 76°C, respectively) and is susceptible to fusion at room temperature
