                            APPENDIX 1 GENERAL INFORMATION
      The specifications given below are strictly for the use of the materials as reagents. The
inclusion of a material in this Appendix does not imply that it is suitable for use in medicines.
For materials or reagents whose availability is limited, a trademark or supplier’s name may
be indicated. It is however acceptable to use reagents from another source provided that
they comply with the standards of the Pharmacopoeia.
                                                 1.1 REAGENTS
        The name of a substance or solution indicates a reagent included in the following list.
The specifications given for reagents do not necessarily guarantee their quality for the
medicine.
        Some of the reagents included may be injurious to health. Important cautions have been
stated for these reagents. They should be handled in accordance with good laboratory
practice and any relevant regulations.
         Reagents in aqueous solution are prepared using water. Where the name of the solvent is
not stated, an aqueous solution is intended.
         Unless otherwise specified, the reagents and reagent solutions are to be stored in
well-closed containers. The labelling should comply with the relevant national legislation.
