Ethyl 2-chloro-4-(1H-pyrazol-1-yl)benzoate CAS 1956355-90-0

Description

Compared with other compounds in its class, the molecular weight of 250.68 g/mol gives Ethyl 2-chloro-4-(1H-pyrazol-1-yl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 2-chloro-4-(1H-pyrazol-1-yl)benzoate (CAS 1956355-90-0), a certified reference material (molecular formula C12H11ClN2O2, MW 250.68 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-chloro-4-(1H-pyrazol-1-yl)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ethyl 2-chloro-4-(1H-pyrazol-1-yl)benzoate 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.
