It sits outside the most-frequent rank tiers, which is often why uncommon words generate more spelling variants per reader.Wiktionary records 2 distinct senses for this headword, so context determines which meaning a reader should apply.

No frequent misspelling variants are recorded for isochron in our index, suggesting the orthography either follows predictable English patterns or the word is uncommon enough that typo corpora lack signal.It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: From iso- + chron. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is isochron, spelled I-S-O-C-H-R-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
