Chemical Structure

Propargyl-PEG4-CH2CH2-Boc CAS 1245823-50-0 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.

Propargyl-PEG4-CH2CH2-Boc (CAS 1245823-50-0), molecular formula C18H32O7 and molecular weight 360.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Propargyl-PEG4-CH2CH2-Boc (C18H32O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 360.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Propargyl-PEG4-CH2CH2-Boc 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.
