Description

The occurrence of 27386-01-2 5-(Methylamino)-1,3,4-thiadiazole-2(3H)-thione 1,3,4-Thiadiazole-2(3H)-thione, 5-(methylamino)- EINECS 248-436-2 5-Mercapto-2-methylamino-1,3,4-thiadiazole NSC 184818 is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

27386-01-2 5-(Methylamino)-1,3,4-thiadiazole-2(3H)-thione 1,3,4-Thiadiazole-2(3H)-thione, 5-(methylamino)- EINECS 248-436-2 5-Mercapto-2-methylamino-1,3,4-thiadiazole NSC 184818 (CAS 27386-01-2) is a high-purity analytical reference standard with the molecular formula C3H5N3S2 and a molecular weight of 147.22 g/mol.

Owing to a nitrile group, sulfur-containing functionality, 27386-01-2 5-(Methylamino)-1,3,4-thiadiazole-2(3H)-thione 1,3,4-Thiadiazole-2(3H)-thione, 5-(methylamino)- EINECS 248-436-2 5-Mercapto-2-methylamino-1,3,4-thiadiazole NSC 184818 is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
