{[(4-chloro-1H-pyrazol-1-yl)methyl]thio}acetic acid CAS 1004643-61-1

Description

Compared with other compounds in its class, the molecular weight of 206.65 g/mol gives {[(4-chloro-1H-pyrazol-1-yl)methyl]thio}acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies {[(4-chloro-1H-pyrazol-1-yl)methyl]thio}acetic acid (CAS 1004643-61-1), a certified reference material (molecular formula C6H7ClN2O2S, MW 206.65 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, {[(4-chloro-1H-pyrazol-1-yl)methyl]thio}acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), {[(4-chloro-1H-pyrazol-1-yl)methyl]thio}acetic acid 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.
