Tris HCl — living evidence map
The Atlas page holds the claims; this is how its evidence evolved.
Summary
Tris is a common biological buffer; stored at 70 C in a peptide formulation it degraded to liberate formaldehyde, which reacted with the peptide's tyrosine residue. · pmid:11536224
Identity
PubChem CID 93573: Tromethamine hydrochloride, C4H12ClNO3, 157.59 g/mol. · pubchem:93573
CAS registry number 1185-53-1. · pubchem:93573
IUPAC name: 2-amino-2-(hydroxymethyl)propane-1,3-diol;hydrochloride. · pubchem:93573
Where the evidence actually sits
Proportion of the 1 claim about Tris 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 Tris 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.
- Approved-label dose · a resolved regulatory document names a labelled dose
nothing resolved on this rung

- Formaldehyde production by Tris buffer in peptide formulations at elevated temperature. · pmid 11536224 · 2001
1 resolved citation, 0 unresolved (an unresolved citation lends nothing). Community volume is its own rung and is never averaged into the evidence rungs.
