1,3-Dimethyl-1h-thieno[2,3-c]pyrazole-5-carboxamide CAS 1098360-43-0

Description

The occurrence of 1,3-Dimethyl-1h-thieno[2,3-c]pyrazole-5-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Dimethyl-1h-thieno[2,3-c]pyrazole-5-carboxamide (CAS 1098360-43-0) is a high-purity analytical reference standard with the molecular formula C8H9N3OS and a molecular weight of 195.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1,3-Dimethyl-1h-thieno[2,3-c]pyrazole-5-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.24 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.
