Description

As a certified reference material (CRM), (3-bromo-5-methylthiophen-2-yl)(1,5-dimethyl-1H-pyrazol-3-yl)methanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(3-bromo-5-methylthiophen-2-yl)(1,5-dimethyl-1H-pyrazol-3-yl)methanol (CAS 1909306-12-2) is a high-purity analytical reference standard with the molecular formula C11H13BrN2OS and a molecular weight of 301.20 g/mol.

Structurally, (3-bromo-5-methylthiophen-2-yl)(1,5-dimethyl-1H-pyrazol-3-yl)methanol (C11H13BrN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 301.20 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
