Chemical Structure

1-Methyl-3-(propan-2-yl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid CAS 1094271-45-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-3-(propan-2-yl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid.

CATO supplies 1-Methyl-3-(propan-2-yl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid (CAS 1094271-45-0), a certified reference material (molecular formula C10H12N2O2S, MW 224.28 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-Methyl-3-(propan-2-yl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.28 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.

CATO manufactures 1-Methyl-3-(propan-2-yl)-1h-thieno[2,3-c]pyrazole-5-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
