答案(中文)
如果您不确定物质的身份,请勿在查询档案的参考物质中包含任何数字标识符(例如 EC、CAS)。相反,请在 IUPAC 名称字段中填写“暂定名称”,后接拟议的代表性化学名称(例如,暂定名称、A 和 B 的反应质量)。在“其他物质标识符”字段中,请参考任何其他相关标识符。请查看屏幕截图以了解详情。在查询结果中收到物质的相应标识符后,请务必在准备注册档案时相应地更新 IUPAC 名称字段。
Answer (EN)
If you are uncertain about your substance’s identity, do not include any numerical identifiers (i.e. EC, CAS) in the reference substance of your inquiry dossier. Instead, write “tentative name” followed by a proposed representative chemical name in the IUPAC name field (e.g. tentative name, Reaction mass of A and B). Refer to any other relevant identifier in the "Other substance identifiers” field. See screenshot for clarity.After receiving the appropriate identifiers for your substance as part of the inquiry outcome, make sure you update the IUPAC name field accordingly when preparing the registration dossier.
