via CultureBotHT
Imported from CultureBotHT. CAS-RN 202185-84-0 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). Used in 4 CultureBot media; samples: R2A_HOMOPIPES, Varel Bryant medium Glucose HOMOPIPES, BHIS_HOMOPIPES…. Curator can promote to a CHEBI primary if/when CHEBI adds the term.

The mapped record carries CAS 202185-84-0 and the expanded exact synonym homopiperazine-1,4-bis(2-ethanesulfonic acid); the unmapped record's Edison review independently identified that same expanded reagent. Preserved the raw and Sigma catalog labels as synonyms; no new SSSOM row is required. |
