Hydrochloride salt — living evidence map
The Atlas page holds the claims; this is how its evidence evolved.
Summary
Hydrochloride is, with acetate, the salt form in which the great majority of therapeutic peptides are marketed; trifluoroacetate salts are viewed less favourably by medicine regulators. · pmid:40365687
History
Trifluoroacetate counterions are commonly exchanged for chloride by freeze-drying the peptide from hydrochloric acid. · pmid:40872554
Identity
Counterion: Hydrochloric Acid, ClH, 36.46 g/mol (PubChem CID 313). · pubchem:313
IUPAC name: chlorane. · pubchem:313
Where the evidence actually sits
Proportion of the 2 claims about Hydrochloride salt standing at each tier. Community volume is shown on the Consensus tab beside this and is never averaged into it.
Living evidence history
2 resolved citations, 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 Hydrochloride salt yet.
Dose evidence, rung by rung
A studied human dose exists on file. Open the rung: the dose is the paper's, in its context, never PepJunkie's.
- Approved-label dose · a resolved regulatory document names a labelled dose
nothing resolved on this rung
- Studied human doses · resolved human studies at the established tier
- Impact of counterion and salt form on the properties of long-acting injectable peptide hydrogels for drug delivery. · pmid 40365687 · 2025
- Observational evidence · resolved human data at the emerging tier: thin, or contested

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