Chemical Structure

Poloxamer 188 CRS CAS 106392-12-5 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 Poloxamer 188 CRS.

CATO supplies Poloxamer 188 CRS (CAS 106392-12-5), a certified reference material (molecular formula C3H6OC2H4O, MW 102.13 g/mol) for analytical method development and quality control.

Structurally, Poloxamer 188 CRS (C3H6OC2H4O) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 102.13 g/mol, it falls into the low-molecular-weight range.

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), Poloxamer 188 CRS 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.
