L-Histidine HCl — living evidence map
The Atlas page holds the claims; this is how its evidence evolved.
Summary
Histidine hydrochloride is widely used in freeze-dried monoclonal antibody formulations; histidine-acetate has been evaluated as an alternative where chloride ions are undesirable. · pmid:41308842
Identity
PubChem CID 165377: Histidine Monohydrochloride Monohydrate, C6H12ClN3O3, 209.63 g/mol. · pubchem:165377
CAS registry number 5934-29-2. · pubchem:165377
IUPAC name: (2S)-2-amino-3-(1H-imidazol-5-yl)propanoic acid;hydrate;hydrochloride. · pubchem:165377
Where the evidence actually sits
Proportion of the 1 claim about L-Histidine HCl standing at each tier. Community volume is shown on the Consensus tab beside this and is never averaged into it.
Living evidence history
1 resolved citation, oldest to newest, coloured by tier. Retractions and contradictions land here as they are recorded.
Structure
No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for L-Histidine HCl yet.
Dose evidence, rung by rung
No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.

1 resolved citation, 0 unresolved (an unresolved citation lends nothing). Community volume is its own rung and is never averaged into the evidence rungs.
