Chemical Structure

tert-Butyl methyl bis-peg3-acid ester CAS 1951439-93-2 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 tert-Butyl methyl bis-peg3-acid ester.

CATO supplies tert-Butyl methyl bis-peg3-acid ester (CAS 1951439-93-2), a certified reference material (molecular formula C15H28O7, MW 320.38 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, tert-Butyl methyl bis-peg3-acid ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), tert-Butyl methyl bis-peg3-acid ester 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.
