tert-Butyl 2-[3-(hydroxymethyl)-5-methyl-1H-pyrazol-1-yl]benzoate CAS 1251950-61-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 2-[3-(hydroxymethyl)-5-methyl-1H-pyrazol-1-yl]benzoate.

tert-Butyl 2-[3-(hydroxymethyl)-5-methyl-1H-pyrazol-1-yl]benzoate (CAS 1251950-61-4), molecular formula C16H20N2O3 and molecular weight 288.34 g/mol, is a CATO reference standard with documented purity and traceability.

tert-Butyl 2-[3-(hydroxymethyl)-5-methyl-1H-pyrazol-1-yl]benzoate (C16H20N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 tert-Butyl 2-[3-(hydroxymethyl)-5-methyl-1H-pyrazol-1-yl]benzoate 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.
