About this H chemical list

What does “starting with H” mean?

The preferred name or a source-listed synonym begins with H, ignoring leading punctuation and numbers. Alphabetic prefixes such as D-, L-, N-, R-, S- and tert- are retained. A record appears once per letter, with its matching names grouped together. The same record can appear under another letter when it has a different name. Source synonyms can include trade names, abbreviations and names in other languages; they are labelled separately from preferred names.

How complete is the database?

This list includes every matching non-obsolete 2-star and 3-star entry with a formula, structure or valid CAS cross-reference in the downloaded ChEBI 256 snapshot. It excludes abstract classes without these substance identifiers. It is complete for that stated scope, not a list of every chemical known worldwide. ChEBI IDs define the records; related chemical forms are not merged solely because a CAS reference overlaps.

What do the data labels mean?

3-star entries are manually annotated by the ChEBI team; 2-star entries are annotated by third parties. “Not supplied” means that the source has no value for the field. CAS numbers are source cross-references with a valid checksum, not independent CAS verification. Formulas and masses retain source notation; the existing PubCAS profiles retain their documented editorial corrections. Search and lookup links may have no matching result.
