Description

Compared with other compounds in its class, the molecular weight of 114.13 g/mol gives 1,2,5-Thiadiazole-3-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2,5-Thiadiazole-3-carbaldehyde (CAS 75238-60-7), molecular formula C3H2N2OS and molecular weight 114.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2,5-Thiadiazole-3-carbaldehyde (C3H2N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 114.13 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
