Chemical Structure

3-[3-(4-Methylpiperidin-1-yl)propyl]-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-4-one CAS 443352-76-9 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

3-[3-(4-Methylpiperidin-1-yl)propyl]-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-4-one (CAS 443352-76-9), molecular formula C17H23N3OS and molecular weight 317.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-[3-(4-Methylpiperidin-1-yl)propyl]-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-4-one (C17H23N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 317.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
