500-structure DFT screens in a single batch — no cluster management required

Define your candidate library, select DFT parameters, submit. Qchemvyx handles job distribution, convergence monitoring, and result ranking. You get an activation-energy-sorted hit list ready for synthesis prioritization.

Screening Pipeline

From library to ranked results in four steps

01

Define Candidate Space

Upload SMILES CSV or SDF. Enumerate ligand variations, metal centers, oxidation states programmatically via API. Up to 500 structures per batch job.

02

Set Screening Parameters

Select functional, basis set, solvent model, and screening reaction (e.g. C-H activation, hydrogenation, oxidative addition). Optionally set convergence thresholds.

03

Submit & Monitor

Qchemvyx distributes jobs across cloud compute. Real-time dashboard shows progress per structure. Partial results accessible as each structure completes.

04

Download Ranked Hits

Results sorted by activation energy. Export to CSV with full energy data, or query via API. Interactive ranking table in dashboard. Direct input to synthesis queue.

Technical Specifications

What a screening batch includes

  • Batch size: Up to 500 structures per screening job
  • Conformer generation: MMFF94 force field, top-3 conformers per structure
  • DFT pre-filter: Optional 6-31G* fast screen before full-basis calculation
  • Convergence: Automatic retry with tighter criteria on failure
  • Turnaround: ~8 hours median for 500-structure B3LYP/6-311G++ batch
  • Priority queue: Express lane option for same-day results
Batch submission (Python SDK)
from qchemvyx import Client

client = Client(api_key="qcvx_...")

# Submit batch from SMILES CSV
batch = client.screening.submit(
    library_csv="candidates.csv",
    reaction="c_h_activation",
    functional="wB97X-D",
    basis_set="6-311G++",
)

results = batch.wait()
# Sorted by activation energy
print(results.top(n=20))
