The present invention relates to a process for determining the suitability for distribution of a batch of rivaroxaban or of a pharmaceutical composition thereof. In particular, it also relates to two impurities of rivaroxaban, to their use as reference markers to determine the purity of a sample of rivaroxaban or a composition thereof, to analytical methods for determining the purity of a sample of rivaroxaban or a composition thereof and to a process of preparing rivaroxaban or pharmaceutical compositions thereof which are free or substantially free of such impurities.

A method of monitoring a parameter of a hydrocarbon well, pipeline or formation is provided. The method comprises introducing a tracer into the hydrocarbon well, pipeline or formation; producing a fluid from the hydrocarbon well, pipeline or formation; and analysing the fluid to determine if the tracer is present in the fluid. The tracer comprises a halogenated thiophene carboxylic or sulfonic acid or a salt of a halogenated thiophene carboxylic or sulfonic acid.
