Lab data & verification
Research use onlySR-17018 batch verification
The consolidated trust layer for every SR-17018 lot — proof of testing, batch verification, quality-control dashboards, Certificates of Analysis, and the five-panel analytical methodology.
Proof of testing
Every lot independently analysed
Each SR-17018 batch is subjected to a five-panel orthogonal workflow — HPLC-UV purity, 1H-NMR identity, LC-MS/MS mass confirmation, GC-HS residual solvents, and Karl Fischer moisture — before a Certificate of Analysis is issued.

Methodology
Five-panel analytical workflow
The orthogonal assay set applied to every SR-17018 lot, from purity quantification through stability screening.
SR-17018 testing methodology
Purity quantification
HPLC-UV
Reversed-phase high-performance liquid chromatography with UV detection at 254 nm. Purity determined by area normalisation against a certified reference standard. Specification: ≥98.0% peak area.
Agilent 1260 Infinity II
Structural confirmation
1H-NMR
Proton nuclear magnetic resonance spectroscopy in CDCl3. Chemical shifts and coupling patterns matched against the SR-17018 reference spectrum to confirm molecular identity and regiochemistry.
Bruker Avance NEO 400 MHz
Mass verification
LC-MS/MS
Liquid chromatography tandem mass spectrometry in positive ESI mode. Protonated molecular ion [M+H]+ observed at m/z 409.08, consistent with the calculated monoisotopic mass of SR-17018 (C19H18Cl3N3O, 408.07 Da).
Thermo Q Exactive Plus
Residual solvents
GC-HS
Headspace gas chromatography with flame ionisation detection. Residual methanol, dichloromethane, and hexane screened against ICH Q3C Class 2 limits. All solvents below reporting threshold.
Agilent 8890 + 7697A HS
Moisture content
Karl Fischer
Coulometric Karl Fischer titration for water content. Specification: ≤0.5% w/w. Low moisture confirms storage stability and minimises hydrolytic degradation risk.
