How is 1-Heptanethiol (CAS: 1639-09-4) typically synthesized?

1-Heptanethiol can be synthesized by the reaction of 1-heptanol with hydrogen sulfide in the presence of a strong acid catalyst, such as hydrochloric acid. The reaction is typically conducted at room temperature and generates 1-Heptanethiol with good yield and selectivity. Alternative methods include the reduction of 1-heptanoyl chloride with sodium sulfide, which is also an effective and common approach.
