## Types

### CreateSaltInput

- `name` (string, required) — The name of the salt. Must be unique (case-insensitive) within the salt library.
- `smiles` (string, required) — The SMILES of the salt's neutral form. The canonical SMILES and molecular formula are derived from it. Immutable after creation.
- `code` (string, optional, nullable) — Optional configurable identifier for this salt (e.g., "HCl"). Must be unique (case-insensitive) across all salts and solvents in the tenant.

### 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, optional)
- `archiveReason` (string, optional, nullable)
- `archived` (boolean, optional)
- `calculatedMolecularWeight` (double, optional, nullable) — The molecular weight of the salt.
- `canonicalSmiles` (string, optional) — The SMILES representation of the salt after standardization.
- `code` (string, optional, nullable) — Optional configurable identifier for this salt (e.g., "HCl", "MS"). Unique across both salts and solvents within a tenant.
- `createdAt` (string, optional)
- `id` (string, optional)
- `modifiedAt` (string, optional)
- `molecularFormula` (string, optional) — The molecular formula (e.g., "HCl").
- `molfile` (string, optional) — The molfile representation of the salt.
- `name` (string, optional)
