- Salt: A Salt is an ionic compound used to represent the salt form of a chemical compound in a tenant's salt library. Salts are referenced when creating molecules to describe the final form of a compound (e.g., hydrochloride, sulfate). Each salt has a required SMILES representing the neutral form, from which the molecular formula is derived.
  - `__typename` string
  - `archiveReason` string, nullable
  - `archived` boolean
  - `calculatedMolecularWeight` number, double, nullable: The molecular weight of the salt.
  - `canonicalSmiles` string: The SMILES representation of the salt after standardization.
  - `code` string, nullable: Optional configurable identifier for this salt (e.g., "HCl", "MS"). Unique across both salts and solvents within a tenant.
  - `createdAt` string, datetime
  - `id` string
  - `modifiedAt` string, datetime
  - `molecularFormula` string: The molecular formula (e.g., "HCl").
  - `molfile` string: The molfile representation of the salt.
  - `name` string
