Chemical Structure

Remifentanil EP Impurity H CAS 968-86-5 chemical structure

Description

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 supplies Remifentanil EP Impurity H (CAS 968-86-5), a certified reference material (molecular formula C19H21N3, MW 291.39 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Remifentanil EP Impurity H is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures Remifentanil EP Impurity H 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.
