Chemical Structure

Pramoxine CAS 140-65-8 chemical structure

Description

CATO supplies Pramoxine (CAS 140-65-8), a certified reference material (molecular formula C17H27NO3, MW 293.40 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Pramoxine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.40 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 Pramoxine 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.
