Homonymy of PubChem CIDs.
| CID | Chemical name | No. of synonyms | No. of homonymic CIDs | No. of synonyms taking homonymic CIDs into account |
|---|---|---|---|---|
| 5355130 | Octinoxate | 88 | 3 | 99 |
| 8572 | Benzophenone-1 | 107 | 1 | 109 |
| 5371084 | Methyl ionone | 64 | 2 | 116 |
| 6448 | Isobornyl acetate | 91 | 10 | 234 |
| 17100 | Terpineol | 119 | 3 | 191 |
| 6549 | Linalool | 118 | 2 | 197 |
| 22311 | Limonene | 253 | 2 | 407 |
| 7585 | alpha-Hexylcinnamaldehyde | 25 | 2 | 111 |
| 107 | Benzylacetate | 170 | 1 | 215 |
| 5590 | 4-tert-Octylphenol monoethoxylate | 193 | 1 | 198 |
| 6623 | Bisphenol A | 189 | 1 | 204 |
| 2347 | Benzyl butyl phthalate | 117 | 1 | 119 |
| 8343 | Bis(2-ethylhexyl) phthalate | 179 | 1 | 182 |
| 7184 | Butyl paraben | 141 | 1 | 145 |
| Fourteen of the 55 chemicals listed by Dodson et al. (2012) had at least one homonymic CID. In some cases, this significantly increased the number of potential synonyms associated with the chemical name. For example, accounting for homonymy increases the number of alpha-hexylcinnamaldehyde synonyms from 25 to 111. | ||||
