答案(中文)
构型异构体(例如对映异构体、非对映异构体)被视为物质的不同组成部分。因此,如果包含构型异构体的物质中存在一种特定异构体,且浓度至少为 80%,则可以将其报告为单一成分物质。请注意,如果提供了强有力的科学依据,则可以接受偏离该规则的情况(请参阅 REACH 和 CLP 物质识别和命名指南第 4.2 节)。
Answer (EN)
Configurational isomers (e.g. enantiomers, diastereoisomers) are regarded as different constituents of a substance. Therefore, a substance which includes configurational isomers may be reported as a mono-constituent substance if one specific isomeric form is present in the substance at a concentration of at least 80%. Note that deviations from the rule are acceptable if a robust scientific justification is provided (see Section 4.2 of the Guidance for identification and naming of substances under REACH and CLP.
